The Pb(II )atom in the title compound, {[Pb(2)(C(7)H(6)NO(2))(4)]}(n), is chelated by two 3-aminobenzoato ligands in a distorted pentagonal-bipyramidal coordination geometry with five oxygen donors in the equatorial positions, one nitro-gen donor and one oxygen donor in the axial positions. Two mol-ecules are linked through a centre of inversion, forming a dinuclear entity. These entities are l...

In the title compound, [Co(C(8)H(5)NO(4))(C(12)H(12)N(2))](n), the Co(II) ion presents a distorted CoO(4)N(2) octa-hedral coordination geometry, formed by three 5-amino-isophthalate dianions and two 1,2-bis-(4-pyrid-yl)ethane ligands. One carboxyl-ate group of the 5-amino-isophthalate dianion chelates a Co cation and the other carboxyl-ate group bridges the other two Co cations, while the termi...

The polymeric title complex, [Co(C(8)H(8)O(5))(H(2)O)(2)](n) was synthesized by reaction of cobalt acetate with 7-oxabicyclo-[2,2,1]heptane-2,3-dicarb-oxy-lic anhydride. The Co(II) ion is six-coordinated in a distorted octa-hedral environment, binding to two water O atoms, to the ether O atom of the bicyclo-heptane unit, to two carboxyl-ate O atoms from two different carboxyl-ate groups of the ...

In the title complex, [Cd(C(2)O(4))(C(12)H(8)N(2))](n), the Cd(II) atom has a distorted octa-hedral coordination, defined by four O atoms from two symmetry-related oxalate ligands and by two N atoms from a bidentate 1,10-phenanthroline ligand. Each oxalate ligand bridges two Cd(II) atoms, generating a zigzag chain structure propagating along [100]. The packing of the structure is consolidated b...

In the title compound, [Cu(C(7)H(3)NO(4))(C(5)H(5)N)](n), the Cu(II) atom is in a slightly distorted octa-hedral coordination environment. Each Cu(II) atom is bound to two N atoms and one O atom of the pyridine-dicarboxyl-ate (PDA) ligand in a tridentate manner, one N atom of the pyridine mol-ecule and two bridging carboxyl-ate O atoms of adjacent PDA ligands, leading to a linear one-dimensiona...

The title compound, [Zn2(C8F4O4)2(C4H8O)2] n , has a three-dimensional metal-organic framework structure. The asymmetric unit consists of two Zn(II) atoms, two tetrahydrofuran ligands, one 2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ate ligand and two half 2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ate ligands, which are completed by inversion symmetry. One Zn(II) atom has a distorted trigon...

In the one-dimensional title coordination polymer, [Co(C(2)O(4))(C(10)H(8)N(2))](n), the Co(II) atom is coordinated in a distorted octa-hedral geometry by two N atoms from one 2,2'-bipyridine ligand and four O atoms belonging to two chelating oxalate ligands. Two neighboring Co centers are bridged by an oxalate ligand, forming a one-dimensional chain structure.

The title compound, {[Cd(2)(C(2)H(3)O(3))(2)(SO(4))(H(2)O)(4)]·H(2)O}(n), was obtained unintentionally in a transmetallation reaction. The crystal structure contains a two-dimensional metal-organic framework based on Cd(II)-(μ-hydroxy-acetato-κ(4)O(1),O(2):O(1),O(1'))-Cd(II) zigzag chains joined together by bridging SO(4) anions. The resulting layers are shifted with respect to each other and a...

In the title coordination polymer, [Pb(C(7)H(5)O(2))(NO(3))(C(10)H(8)N(2))](n), the Pb(II) ion is eight-coordinated by two N atoms from one 2,2'-bipyridine ligand, two O atoms from one benzoate anion and four O atoms from three nitrate groups (one chelating, two bridging) in a distorted dodecahedral geometry. Adjacent Pb(II) ions are linked by bridging nitrate O atoms through the central Pb(2)O...

In the asymmetric unit of the title polymeric compound, [Co(C(8)H(4)O(4))(C(5)H(5)N)(2)](n), there are two crystallographically independent Co(II) atoms, each of which is six-coordinated in a distorted octa-hedral geometry by four O atoms from benzene-dicarboxyl-ate anions and two N atoms from pyridine ligands. The benzene-dicarboxyl-ate dianions bridge the Co(II) atoms into a tape running alon...
