ABSTRACT: The title compound, [Fe(2)Ni(C(17)H(14)Br(2)N(2)O(2))(2)(CN)(4)(H(2)O)(2)] or [{Fe(C(17)H(14)Br(2)N(2)O(2))(H(2)O)}(2)(μ-CN)(2){Ni(CN)(2)}], is iso-structural with its Mn(III)-containing analogue. Each Fe(III) atom is chelated by a Schiff base ligand via two N and two O atoms and is additionally coordinated by a water mol-ecule, forming a slightly distorted octa-hedral geometry. The two Fe(III) centres are bridged by a square-planar Ni(CN)(4) unit, which lies on an inversion centre. A two-dimensional network is formed via O-H⋯O and O-H⋯N hydrogen bonds.

Project description:In the title compound, [Mn(2)Ni(C(17)H(14)Br(2)N(2)O(2))(2)(CN)(4)(H(2)O)(2)] or [{Mn(C(17)H(14)Br(2)N(2)O(2))(H(2)O)}(2)(μ-CN)(2){Ni(CN)(2)}], each Mn(III) atom is chelated by a Schiff base ligand via two N and two O atoms and is additionally coordinated by a water mol-ecule to give a slightly distorted octa-hedral geometry. Two such Mn(III) ions are linked by a square-planar Ni(CN)(4) unit, which lies on an inversion centre. A two-dimensional network is formed by O-H⋯O and O-H⋯N hydrogen bonds.

Project description:The title complex, {[Fe(II)Y(III)(CN)(4)(NO(3))(C(10)H(8)N(2))(CH(3)OH)(3)]·CH(3)OH·0.5H(2)O}(n), is built up of ladder-like chains oriented along the c axis. Each ladder consists of two strands based on alternating Fe(II) and Y(III) ions connected by cyanide bridges. Two such parallel chains are connected by additional cyanide anions (the 'rungs' of the ladder), which likewise connect Fe(II) and Y(III) ions, such that each [Fe(bipy)(CN)(4)](2-) (bipy is 2,2'-bipyridine) unit coordinates with three Y(III) ions and each Y(III) ion connects with three different [Fe(bipy)(CN)(4)](2-) units. The Fe(II) atom is six-coordinated in a distorted octa-hedral geometry and the Y(III) atom cation is eight-coordinated in a distorted dodeca-hedral environment. The uncoordinated methanol solvent mol-ecules are involved in hydrogen-bonding inter-actions with the one terminal cyanide group and a coordinated methanol mol-ecule from another [Y(III)(NO(3))(CH(3)OH)(3)](2+) unit. Adjacent ladder-like chains are also held together by hydrogen bonds between the terminal cyanide ligands of the [Fe(CN)(4)(bipy)](2-) units in one chain and the OH donors of CH(3)OH ligands from [Y(III)(NO(3))(CH(3)OH)(3)] units in neighboring chains. The water molecule exhibits half-occupation.

Triaqua-1κO-μ-cyanido-1:2κN:C-penta-cyanido-2κC-tetra-kis-(dimethyl-formamide-1κO)-1-holmium(III)-2-iron(III) monohydrate.

Project description:In the bimetallic cyanide-bridged title complex, [Fe(0.98)HoRu(0.02)(CN)(6)(C(3)H(7)NO)(4)(H(2)O)(3)]·H(2)O, the Ho(III) ion is in a slightly distorted square-anti-prismatic arrangement formed by seven O atoms from four dimethyl-formamide (DMF) mol-ecules and three water mol-ecules, and one N atom from a bridging cyanide group connected with the Fe(III) atom which is octa-hedrally coordinated by six cyanide groups. In the crystal, mol-ecules are held together through O-H⋯N and O-H⋯O hydrogen-bonding inter-actions to form a three-dimensional framework. Elemental analysis of one of the precursors and the crystal shows that there is a slight contamination of Fe by Ru. The Fe site displays, therefore, small substitutional disorder with site-occupancy factors Fe/Ru = 0.98:0.02. The two methyl groups of two dimethyl-formamide ligands are positionally disordered with site-occupancy factors of 0.44 (3):0.56 (3) and 0.44 (3):0.56 (3).

Project description:The hydro-thermal reaction of CoCl(2)·6H(2)O, 1,10-phenanthroline (phen) and K(3)[Fe(CN)(6)] in deionized water yielded the title cyanide-bridged trinuclear cluster, [Co(2)Fe(CN)(8)(C(12)H(8)N(2))(4)]·4H(2)O or [{Co(III)(phen)(CN)(4)}(2){Fe(II)(phen)(2)}]·4H(2)O, which contains two Co(III) centers and one Fe(II) center linked by cyanide bridges. The combination of coordinative bonds, O-H⋯N and O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.630 (2) Å] results in the stabilization of a supra-molecular structure. All uncoordinated water molecules are disordered. Thermogravimetric analysis reveals that the title complex loses the four crystal water mol-ecules at about 333 K, then the anhydrous phase loses no further mass up to about 573 K, above which decomposition occurs.

Project description:The title compound, [Sn(4)(C(8)H(17))(8)O(2)(C(6)H(5)N(2)O(2))(4)], is a tetra-nuclear Sn(IV) complex, built up by inversion symmetry around the central Sn(2)O(2) ring. The Sn(IV) coordination geometries are distorted SnO(3)C(2) trigonal-bipyramidal and distorted SnO(4)C(2) octa-hedral. The three-coordinate μ(3)-oxido bridging O atom in the Sn(2)O(2) ring is attached to three Sn atoms. All non-H atoms, with the exception of the Sn-bonded octyl groups, lie approximately on a non-crystallographic mirror plane.

The coordination polyhedron about the two central Sn atoms is distorted trigonal-bipyramidal, whilst the two peripheral metal atoms bonded to the carboxyl-ate groups have a distorted octa-hedral coordination geometry. In the crystal, mol-ecules are connected by long Sn⋯O contacts [3.139 (11) Å], forming chains along [011].

Di-μ(2)-acetato-1:2κO:O';2:3κO:O'-bis-(N,N'-dimethyl-formamide)-1κO,3κO-bis-{μ(2)-2,2'-[propane-1,3-diylbis(imino-methyl-ene)]diphenolato-1κO,N,N',O':2κO,O';2κO,O':3κO,N,N',O'-1,3-dinickel(II)-2-cadmium(II).

Project description:The crystal structure of the title compound, [Ni(2)Cd(C(17)H(16)N(2)O(2))(2)(C(2)H(3)O(2))(2)(C(3)H(7)NO)(2)], contains discrete centrosymmetric hetero-trinuclear mol-ecules in which Ni/Cd atom pairs are triply bridged via O atoms from the SALPD(2-) [N,N'-bis-(salicyl-idene)-1,3-propane-diaminate] and acetate ligands. The central Cd(II) ion is in a distorted octa-hedral coordination environment formed by four O atoms from two SALPD(2-) ligands in the equatorial plane and two O atoms of two symmetry-related acetate ligands in the axial positions. The symmetry-related Ni(II) ions are in slightly distorted octa-hedral environments, coordinated by two O and two N atoms from tetra-dendate SALPD(2-) ligands in the equatorial plane, while the axial positions are occupied by O atoms from a dimethyl-formamide and an acetate ligand. This results in the formation of three edge-shared octa-hedra in which the Ni⋯Cd distance is 3.1482 (15) Å. The crystal structure is stabilized by weak C-H⋯O hydrogen bonds.

The Na atom is chelated by the four O atoms of the Schiff base ligand, and coordinated by a methanol mol-ecule and a perchlorate anion. The six-coordinate Na atom adopts a distorted octa-hedral coordination geometry. The O atoms of the perchlorate anion are disordered over two sites with site-occupancy factors of 0.697 (5) and 0.303 (5). O-H⋯O hydrogen bonding occurs.

Project description:The mol-ecule of the title compound, [NaNi(C(18)H(18)N(2)O(4))(ClO(4))(CH(3)OH)], is almost planar, the maximum deviation from the molecular plane being 5.3 (1) Å. The Ni(2+) ion is N(2)O(2) coordinated by the Schiff base ligand, leading to a slightly distorted square-planar environment. The Na atom is chelated by the four O atoms of the Schiff base ligand and is coordinated by the O atoms of a methanol ligand and a perchlorate anion. The perchlorate ion is disordered over two sites with occupancies 0.723 (12):0.277 (12).

Project description:In the title compound, [Cr(2)Ni(C(16)H(14)N(2)O(2))(2)(CN)(4)(C(10)H(24)N(4))]·2CH(3)OH, each [Cr(salen)(CN)(2)] unit {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate} acts as a monodentate ligand through one of its two cyanide groups N bound to a central [Ni(cyclam)](2+) core (cyclam is 1,4,8,11-tetra-azacyclo-tetra-deca-ne). Each Cr(III) ion is coordinated by two N and two O atoms from a salen ligand situated in the equatorial plane with two trans cyanide C atoms, yielding a distorted octa-hedral coordination geometry. The Ni(II) atom lies on an inversion center and is octa-hedrally coordinated by a cyclam ligand lying in the equatorial plane and by two cyanide N atoms. The asymmetric unit contains one half of the complex mol-ecule and a methanol solvent mol-ecule. In the crystal structure, the complex mol-ecule is linked to the methanol solvent mol-ecules via O-H⋯O and N-H⋯O hydrogen bonds. Individual complex mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains along b.
