Catena-Poly[[[aqua-(2,2'-bipyridine-?(2) N,N')zinc]-?-furan-2,5-dicarboxyl-ato-?(2) O (2):O (5)] dihydrate].

ABSTRACT: In the title hydrated coordination polymer, {[Zn(C6H2O5)(C10H8N2)(H2O)]·2H2O} n , an infinite [1-10] chain is formed by the linking of [Zn(C10H8N2)(H2O)](2+) entities by bridging, monodentate furan-2,5-dicarboxyl-ate dianionic linkers. The Zn(2+) coordination geometry is a trigonal bipyramid, with one N atom (from 2,2'-bipyridine) and one O atom (from the bridging dianion) in the axial positions. For each Zn(II) atom, the dihedral angle between the furan ring of its coordinated bridging ligand and its coordinated bipyridine ring system is 87.19?(8)°. O-H?O hydrogen bonds involving both the coordinated and uncoordinated water mol-ecules generate a layer motif parallel to (001).

Project description:In the centrosymmetric title compound, [Co(2)(C(7)H(3)NO(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the two Co(II) cations are bridged by pairs of pyridine-2,5-dicarboxyl-ate anions across an inversion center.

In the chain, O(water)-H?O hydrogen bonds are present, while adjacent chains are linked by O(methanol)-H?O hydrogen bonds into a layer parallel to (10-2).

These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.

Project description:In the title compound, [Ni(C(14)H(8)O(4))(C(10)H(8)N(2))(H(2)O)(2)](n), the Ni(II) atom is coordinated in a slightly distorted octa-hedral geometry by two water mol-ecules, two N atoms from a 2,2'-bipyridine ligand and two O atoms from the carboxyl-ate groups of two 2,2'-biphenyl-dicarboxyl-ate (2,2'-dpa) ligands. The 2,2'-dpa ligand acts as a bridge between neighbouring Ni(II) atoms, forming one-dimensional coordination polymers along [100]. The coordinated water mol-ecules form hydrogen bonds to the carboxyl-ate O atoms of 2,2'-dpa within the same coordination polymer, and one O-H⋯π inter-action is also formed to 2,2'-dpa.
