Crystal structure of cis-bis-(μ-β-alanine-κ(2) O:O')bis[tri-chlorido-rhenium(III)](Re-Re) sesquihydrate.

ABSTRACT: The structure of the title compound, [Re2Cl6(C3H7NO2)2]·1.5H2O, comprises a dinuclear complex cation [Re-Re = 2.2494 (3) Å] involving cis-oriented double carboxyl-ate bridges, four equatorial chloride ions and two weakly bonded chloride ligands in the axial positions at the two rhenium(III) atoms. In the crystal, two complex mol-ecules and two water mol-ecules constitute hydrogen-bonded dimers, while an extensive hydrogen-bonding network involving the groups of the zwitterionic ligand is important for generation of the framework. An additional partially occupied water molecule is disordered over two sets of sites about a symmetry centre with a site-occupancy ratio of 0.3:0.2.

Crystal structure of tetra-kis-(μ-n-butyrato-κ(2) O:O')bis-[chlorido-rhenium(III)](Re-Re).

Project description:With an inversion center at the mid-point of the two Re(III) atoms, the title compound, [Re2Cl2{O2C(CH2)2CH3}4], exhibits a paddle-wheel or lantern-type structure with four n-butyrate groups bridging two Re(III) atoms in a syn-syn fashion. The axial chloride ligands together with the Re-Re quadruple bond [2.2330 (3) Å] complete an essentially octa-hedral geometry around each Re(III) atom. There is little distortion, with an Re-Re-Cl bond angle of 176.18 (3)° and typical cis-O-Re-O bond angles ranging from 89.39 (11) to 90.68 (11)°. There are two mol-ecules in the unit cell, and no significant inter-molecular inter-actions were noticed between mol-ecules in the crystal.

Crystal structure of di-μ-isobutyrato-κ(4) O:O'-bis-[cis-di-chlorido-(dimethyl sulfoxide-κS)rhenium(III)].

Project description:The title compound, [Re2(C3H7COO)2Cl4{(CH3)2SO}2], comprises binuclear complex mol-ecules [Re-Re = 2.24502 (13) Å] involving cis-oriented double carboxyl-ate bridges, four equatorial chloride ions and two weakly bonded O atoms from dimethyl sulfoxide ligands in the axial positions at the Re(III) atoms. In the crystal, mol-ecules are linked into corrugated layers parallel to (101) by very weak C-H⋯Cl and C-H⋯O hydrogen-bonding inter-actions. C-H⋯Cl hydrogen bonding provides the links between layers to consolidate a three-dimensional framework.

Project description:The title compound, {systematic name: (3-carb-oxy-1-ethyl-6-fluoro-7-piperazin-4-ium-1-yl-1H-quinolin-4-yl-idene)oxonium tri-μ(2)-chlorido-bis-[trichloridobismuthate(III)] chloride dihydrate], (C(16)H(20)FN(3)O(3))(2)[Bi(2)Cl(9)]Cl·2H(2)O, is composed of [Bi(2)Cl(9)](3-) anions lying on crystallographic twofold rotation axes, Cl(-) anions also on twofold axes, C(16)H(20)FN(3)O(3) (2+) cations, and water mol-ecules. The Bi(III) coordination polyhedron is a distorted octa-hedron and two such octa-hedra share a triangular face to form the complex anion. There are three short terminal Bi-Cl bonds [2.5471 (6)-2.5781(5 Å] and three longer bridging bonds [2.8599 (5)-2.9984 (6) Å] in each octa-hedron. Anions, cations and water mol-ecules are linked by hydrogen bonds to form a three-dimensional network. There are also π-π stacking inter-actions between quinoline ring systems, with an inter-planar distance of 3.27 (1) Å.

trans-Bis(μ-benzene-thiol-ato-κ(2) S:S)bis[chlorido-(tri-phenyl-phosphane-κP)palladium(II)] chloro-form disolvate.

Project description:The title compound, [Pd2Cl2(C6H5S)2(C18H15P)2]·2CHCl3, contains a centrosymmetric dinuclear palladium complex with the Pd(II) cation in a slightly distorted square-planar coordination environment. The Pd(II) cations are bridged by the S atoms of two benzene-thiol-ate ligands with different Pd-S distances [2.2970 (11) and 2.3676 (11) Å]. The coordination of the metal atom is completed by a chloride anion [2.3383 (11) Å] and a tri-phenyl-phosphane ligand [2.2787 (11) Å]. Weak C-H⋯Cl inter-actions are present between complex mol-ecules and the CHCl3 solvent mol-ecule. The latter is disordered over two positions in a 0.792 (8):0.208 (8) ratio. The crystal under investigation was found to be twinned by nonmerohedry, with a fraction of 73.4 (1)% for the major twin component.

Tri-μ-chlorido-bis-[(η-hexa-methyl-benzene)-ruthenium(II)] tetra-chlorido-ferrate(III).

Project description:The mol-ecular geometry of the complex cation in the title structure, [(μ-Cl)(3){Ru(II)(η(6)-C(6)Me(6))}(2)][Fe(III)Cl(4)], compares very well with that reported earlier for the corresponding PF(6) (-) salt [Pandey et al. (1999 ▶). J. Organomet. Chem.592, 278-282]. The [FeCl(4)](-) counter ion has a rather regular tetra-hedral geometry with Fe-Cl distances and Cl-Fe-Cl angles in the range 2.1891 (7)-2.2018 (8) Å and 107.10 (3)-110.56 (3)°, respectively. There are no significant inter-molecular inter-actions in the crystal except for some weak C-H⋯Cl contacts, which in turn indicates that the crystal packing is determined predominantly by electrostatic inter-actions between the ionic constituents.

The crystal structures of tetra-kis-(μ-n-butyrato-κ(2) O:O')bis[bromidorhenium(III)] and tetra-kis-(μ-n-butyrato-κ(2) O:O')bis[chlorido-rhenium(III)] aceto-nitrile disolvate.

Project description:The title complexes, [Re2Br2(O2CC3H7)4], (1), and [Re2(O2CC3H7)4Cl2]·2CH3CN, (2), both exhibit paddlewheel structures with four carboxyl-ate ligands bridging two Re(III) atoms. The Re-Re distances are 2.2325 (2) and 2.2299 (3) Å, indicating quadruple bonds between the Re(III) atoms in each complex. Both complexes contain an inversion center at the mid-point of the Re-Re bond. The Re-Br bond [2.6712 (3) Å] in (1) is 0.1656 (6) Å longer than the Re-Cl distance [2.5056 (5) Å] of (2). In (2), the N atom of each co-crystallized aceto-nitrile solvent mol-ecule is nearly equidistant between and in close contact with two carboxyl-ate C atoms.

[μ-3,3'-Bis(tri-hydro-bor-yl)[3]ferroceno-phane]bis-(chlorido-zirconocene).

Project description:The title compound, [FeZr2(C5H5)4Cl2(C13H18B2)], is a heteronuclear complex that consists of a [3]ferrocenophane moiety substituted at each cyclo-penta-dienyl (Cp) ring by a BH3 group; the BH3 group is bonded via two H atoms to the Zr atom of the zirconocene chloride moiety in a bidentate fashion. The two Cp rings of the [3]ferrocenophane moiety are aligned at a dihedral angle of 8.9 (4)° arising from the strain of the propane-1,3-diyl bridge linking the two Cp rings. [One methyl-ene group is disordered over two positions with a site-occupation factor of 0.552 (18) for the major occupied site.] The dihedral angles between the Cp rings at the two Zr atoms are 50.0 (3) and 51.7 (3)°. The bonding Zr⋯H distances are in the range 1.89 (7)-2.14 (7) Å. As the two Cp rings of the ferrocene unit are connected by an ansa bridge, the two Zr atoms approach each other at 6.485 (1) Å. The crystal packing features C-H⋯Cl inter-actions.

Bis(μ-l-arginine-κ(3) N (2),O:O')bis-(l-arginine-κ(2) N (2),O)tetra-μ-chlorido-tetra-chlorido-tetra-copper(II).

Project description:The title compound, [Cu4Cl8(C6H14N4O2)4], contains four mol-ecules in the asymmetric unit. In the mol-ecular structure, each of the four Cu(2+) ions binds to three Cl atoms, one N atom and one O atom, resulting in distorted square-pyramidal coordination environments. The molecular structure is stabilized by weak C-H⋯O and N-H⋯Cl hydrogen bonds. The crystal structure exhibit weak inter-molecular N-H⋯O, C-H⋯O and N-H⋯Cl inter-actions, generating a three-dimensional network.

Di-μ-chlorido-bis-[(2-amino-benzamide-κ(2) N (2),O)chlorido-copper(II)].

Project description:The title compound, [Cu2Cl4(C7H8N2O)2], crystallizes as discrete [CuLCl2]2 (L = 2-amino-benzamide) dimers with inversion symmetry. Each Cu(II) ion is five-coordinated and is bound to two bridging chloride ligands, a terminal chloride ligand and a bidentate 2-amino-benzamide ligand. The crystal structure exhibits alternating layers parallel to (010) along the b-axis direction. In the crystal, the components are linked via N-H⋯Cl hydrogen bonds, forming a three-dimensional network. These inter-actions link the mol-ecules within the layers and also link the layers together and reinforce the cohesion of the structure.
