Tetra-sodium (dihydrogenhepta-oxido-digermanato)bis-(dihydrogentetra-oxido-germanato)dicopper(II) monohydrate.

ABSTRACT: In the hydro/solvothermally synthesized title compound, Na(4)[Cu(2)(H(2)Ge(2)O(7))(H(2)GeO(4))(2)]·H(2)O, the framework building units include CuO(4), GeO(2)(OH)(2) and GeO(3)(OH) tetra-hedra, the latter being condensed into H(2)Ge(2)O(7) (4-) dimers. All the tetra-hedra are connected by corner-sharing into four-membered-ring (4MR) secondary building units containing two CuO(4), one GeO(2)(OH)(2) and one GeO(3)(OH) entity. The 4MRs form chains by corner-sharing the Cu unit and adjacent chains are linked by H(2)Ge(2)O(7) (4-) dimers, generating layers containing ten-membered rings. Three sodium cations (one with site symmetry and one with site symmetry 2) and a water mol-ecule (O-atom site symmetry 2) complete the structure. A network of O-H?O hydrogen bonds helps to consolidate the packing.

Tetra-aqua-bis[?-N-(5-nitro-2-oxido-benzyl-idene)glycylglycinato]manganese(II)dinickel(II) tetra-hydrate.

Project description:The two unique Ni(II) atoms of the title complex, [MnNi(2)(C(11)H(8)N(3)O(6))(2)(H(2)O)(4)]·4H(2)O, have a slightly distorted square-planar coordination environment with a tetra-dentate N-(5-nitro-2-oxidobenzyl-idene)glycylglycinate Schiff base trianion. The Ni(II) atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxyl-ate O atom. The Mn(II )atom is connected via the carboxyl-ate groups, forming a hetero-trinuclear Ni(II)-Mn(II)-Ni(II) system. The Mn(II) atom is six-coordinated in an octa-hedral geometry by four O atoms from two carboxyl-ate groups and four water mol-ecules. The Ni(II)-Mn(II)-Ni(II) hetero-trinuclear mol-ecules are stacked in the crystal and cross-linked through O-H?O hydrogen bonds.

Project description:In the centrosymmetric dinuclear Cu(II) title complex, [Cu(2)(C(18)H(16)Cl(4)N(2)O(2))(2)], the Cu(II) atom adopts a square-pyramidal geometry with a tetra-dentate ligand in the basal plane.

Chlorido{?-2,6-bis-[(2-amino-eth-yl)imino-meth-yl]-4-chloro-phenolato}-?-oxido-dicopper(II) trihydrate.

Project description:In the title dinuclear complex, [Cu(2)(C(14)H(20)ClN(4)O)ClO]·3H(2)O, one Cu(II) cation assumes a distorted square-planar coordination geometry and the other a distorted square-pyramidal coordination geometry. Both Cu(II) cations are N,N',O-chelated by one arm of the 2,6-bis-[(2-amino-eth-yl)imino-meth-yl]-4-chloro-phenolate anion, and one oxide anion bridges the two Cu(II) cations, forming a dinuclear complex. One of the Cu(II) cations is further coordinated by an Cl(-) anion in the apical direction. In the crystal, lattice water mol-ecules are linked with the complex mol-ecule via O-H?Cl hydrogen bonds while O-H?O hydrogen bonding occurs between lattice water mol-ecules , forming three-dimensional network structure.

Poly[bis-(2,2'-bipyridine-?N,N')deca-?-oxido-dioxidodicopper(II)tetra-vanadium(V)].

Project description:The title compound, [Cu(2)V(4)O(12)(C(10)H(8)N(2))(2)](n), shows a two-dimensional copper-vanadate layer composed of eight-membered rings, each containing four corner-sharing VO(4) tetra-hedra; these are linked through six penta-coordinated Cu(II) atoms with the 2,2'-bipyridine ligands attached and pointing above and below the plane of the layer. The Cu atom is coordinated by two N donors from the 2,2'-bipyridine ligand and three O atoms from three adjacent VO(4) units to form a distorted tetragonal pyramid. These layers are further connected by ?-? inter-actions between inter-leaving bipyridine ligands of adjacent layers [centroid-centroid distances = 3.63?(1) and 3.68?(1)?Å] into a three-dimensional supra-molecular structure.

Tetra-kis(?-acetato-?(2)O:O')-bis-[(3-pyridine-carboxaldehyde-?N')]dicopper(II)(Cu-Cu).

Project description:The binuclear title compound, [Cu(2)(CH(3)CO(2))(4)(C(6)H(5)NO)], is located about a center of inversion. The Cu(II) atoms are connected [Cu-Cu = 2.6134?(5)?Å] and bridged by four acetate ligands.

In the crystal, the complex mol-ecules are linked by C-H?O hydrogen bonds, forming two-dimensional networks lying parallel to the ab plane. These networks are linked via C-H?O hydrogen bonds involving inversion-related 3-pyridinecarboxaldehyde ligands, forming a three dimensional supra-molecular architecture.

Project description:In the title compound, {[Cu2Na2(C10H2O8)1.5(H2O)6]·H2O} n , the Cu(2+) ion is hexa-coordinated by five O atoms from benzene-1,2,4,5-tetra-carboxyl-ate (btec(4-)) ligands and one water mol-ecule.

CuO6 and NaO6 octa-hedra are connected, forming bi-dimensional layers. These layers, which extend parallel to the ac plane, are further inter-connected by ?10- or ?11-bridging btec(4-) ligands and by O-H?O hydrogen bonds, involving both btec(4-) ligands and water mol-ecules, forming a three-dimensional network.
