Redetermination of poly[aquadi-μ(3)-oxy-diacetato-dicopper(II)].

ABSTRACT: The title complex, [Cu(2)(C(4)H(4)O(5))(2)(H(2)O)](n), has a two-dimensional layer structure. The Cu atom has a distorted octa-hedral (CuO(6)) environment and is coordinated by four carboxyl-ate group O atoms from three different oxydiacetate ligands in a planar arrangement and one half-occupancy water mol-ecule and an ether O atom in the axial positions. In the crystal structure, weak intra- and inter-molecular O-H⋯O hydrogen bonds help to stabilize the crystal packing. The structure has already been published [Whitlow & Davey (1975 ▶). J. Chem. Soc. Dalton. Trans. pp. 1228-1232]; this redetermination reports the structure with higher precision.

Poly[octa-aquadi-μ-phosphato-trinickel(II)].

Project description:In the title compound, [Ni(3)(PO(4))(2)(H(2)O)(8)](n), which was synthesized hydro-thermally, all the Ni atoms are located in slightly distorted octa-hedral coordination environments. Two phosphate groups and two Ni atoms share a centrosymmetric four-membered ring and an eight-membered ring such that the four-membered ring is inside the eight-membered ring. The eight-membered rings are connected with the other Ni atoms (lying on centres of symmetry) through phosphate anions, generating a one-dimensional chain structure. Adjacent chains are connected through hydrogen bonds, forming a three-dimensional network.

Poly[diimidazole-μ(4)-oxalato-μ(2)-oxalato-dicopper(II)].

Project description:The title compound, [Cu(2)(C(2)O(4))(2)(C(3)H(4)N(2))(2)](n), was obtained as an unexpected product under hydro-thermal conditions. The Cu(II) atom is in a Jahn-Teller-distorted octa-hedral environment formed by one imidazole N atom and five O atoms from three oxalate anions. The two independent oxalate anions are situated on centres of inversion and coordinate to the Cu(II) atom in two different modes, viz. bidentate and monodentate. The bidentate anions bridge two Cu(II) atoms, whereas the monodentate anions bridge four Cu(II) atoms, leading to a layered arrangement parallel to (100). These layers are further linked into a final three-dimensional network structure via inter-molecular N-H⋯O hydrogen bonds. The title compound is isotypic with the Zn analogue.

Project description:In the title compound, [Cu(C(10)H(8)O(6))(C(5)H(5)N)(2)(H(2)O)](n), the Cu atom is five-coordinated by two O atoms from two carboxyl-ate groups of two different 2,2'-(p-phenyl-enedi-oxy)diacetate ligands, two N atoms from two pyridine mol-ecules and one water O atom. The geometry is square-pyramidal with the water O atom occupying the apical position. The carboxyl-ate group bridges adjacent Cu atoms, forming an infinite zigzag chain extending parallel to [001]. The chains are linked into layers by O-H⋯O hydrogen bonds. The Cu and water O atoms lie on special positions of site symmetry 2.

A redetermination of the structure and Hirshfeld surface analysis of poly[di-aquadi-μ-hydroxido-tetra-kis-(μ-nicotinato <i>N</i>-oxide)tricopper(II)].

Project description:The product obtained from the reaction of pyridine-2,3-di-carb-oxy-lic acid and hydrated copper(II) chloride in hot aqueous NaOH solution was determined by low temperature X-ray diffraction to be [Cu3(C6H4NO3)4(OH)2(H2O)2] n or [Cu3(μ-OH)2(μ-nicNO)4(H2O)2] n (nicNO is pyridine-3-carboxyl-ate N-oxide), a structure obtained from room temperature data and reported previously. The present determination is improved in quality and treatment of the H atoms. A Hirshfeld surface analysis of the inter-molecular inter-actions is presented.

Poly[[tetra-aqua-bis[μ(4)-2,2'-(p-phenyl-ene-di-oxy)diacetato][μ(2)-2,2'-(p-phenyl-ene-di-oxy)diacetato]dierbium(III)] hexa-hydrate].

Project description:The asymmetric unit of the title compound, [Er(2)(C(10)H(8)O(6))(3)(H(2)O)(4)]·6H(2)O, comprises one Er(3+) ion, one and a half 2,2'-(p-phenyl-enedi-oxy)diacetate (hqda) ligands, two coordinated water mol-ecules and three uncoordinated water mol-ecules. The Er(3+) ion is nine-coordinated by seven O atoms from hqda ligands and two O atoms from water mol-ecules. In the title compound, there are two types of crystallographically independent ligands: one with an inversion center in the middle of the ligand is chelating on both ends of the ligand towards each one Er center; the other hqda ligands are bridging-chelating on one side, and bridging on the other end of the ligand. Two adjacent Er(3+) ions are thus chelated and bridged by -COO groups from hqda ligands in three coordination modes (briding-chelating, bridging and chelating). These building blocks are linked by OOC-CH(2)O-C(6)H(4)-OCH(2)-COO spacers, forming two-dimensional neutral layers. Adjacent layers are linked by O-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional supermolecular network.

Project description:The title dysprosium coordination polymer, {[Dy(2)(C(10)H(8)O(6))(3)(H(2)O)(2)]·2H(2)O}(n), was synthesized by reacting dysprosium(III) nitrate and the flexible ligand (p-phenyl-enedi-oxy)diacetic acid under hydro-thermal conditions. Each Dy(III) ion is coordinated by nine O atoms in a tricapped trigonal prismatic geometry. The DyO(9) polyhedra form layers parallel to the bc plane. The rigid benzene rings of the anions link the layers along the a axis, forming a three-dimensional framework.

Poly[diaqua-(μ-4,4'-bipyridine-κN:N')[μ-2,2'-(p-phenyl-enedi-oxy)diacetato-κO:O']cadmium].

Project description:In the title compound, [Cd(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2)](n), the Cd(II) ion has inversion symmetry and is coordinated by O atoms from two water mol-ecules and two bridging 2,2'-(μ-p-phenyl-enedi-oxy)diacetate ligands and two N atoms from two 4,4'-bipyridine ligands, giving a slightly distorted octa-hedral geometry. The diacetate and 4,4'-bipyridine ligands also lie across inversion centers. The bridging ligands form layers parallel to (11[Formula: see text]), with adjacent layers inter-connected via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate O atoms, giving a three-dimensional supra-molecular architecture.

catena-Poly[[[triaqua-cadmium(II)]-μ-2,2'-[oxalylbis(azanediyl)]diacetato-κO,O'] dihydrate].

Project description:The structure of the polymeric title complex, {[Cd(C(6)H(6)N(2)O(6))(H(2)O)(3)]·2H(2)O}(n), consists of chains running parallel to [01] in which the oxamidato ligand, deprotonated only at the carboxyl-ate groups, acts as a bridging bis-monodentate ligand. The Cd atom and the O atom of a coordinated water mol-ecule are located on a twofold axis. The coordination geometry around the Cd atom is distorted trigonal-pyramidal. In the crystal structure, neighbouring chains are linked into a three-dimensional network by inter-chain O-H⋯O and N-H⋯O hydrogen bonds.

Poly[[diaqua-nickel(II)]-μ(2)-4,4'-bipyridine-κN:N'-μ-p-phenyl-enedioxy-diacetato-κO:O'].

Project description:The title coordination polymer, [Ni(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2)](n), was obtained by the hydro-thermal reaction of nickel(II) sulfate, benzene-1,4-dioxy-diacetic acid (p-phenyl-enedioxy-diacetic acid) and 4,4'-bipyridine (4,4'-bpy) in alkaline aqueous solution. Each Ni(II) atom is coordinated by two O atoms from two benzene-1,4-dioxy-diacetate ligands, two N atoms from two 4,4'-bpy ligands and two water mol-ecules, and displays a distorted octa-hedral geometry. The Ni(II) atom and benzene-1,4-dioxy-diacetate and 4,4'-bpy moieties lie on inversion centres. The benzene-1,4-dioxy-diacetate ligands bridge the Ni(II) atoms to form infinite zigzag chains, which are further inter-connected by 4,4'-bpy ligands to form a grid-like layer parallel to the (01) plane. Moreover, there are O-H⋯O hydrogen-bonding inter-actions within the grid-like layer between the coordinated water mol-ecules and the carboxyl-ate O atoms.
