Catena-Poly[[diaqua-nickel(II)]-bis-(?-pyridine-4-sulfinato)-?N,O;?O,N].

ABSTRACT: In the title coordination polymer, [Ni(C(5)H(4)NO(2)S)(2)(H(2)O)(2)](n), the Ni(II) ion is located on an inversion centre and is octa-hedrally coordinated by two N and two O atoms of four symmetry-related and deprotonated pyridine-4-sulfinate (ps) ligands together with two water mol-ecules in axial positions. The ps(-) anions, acting as ?(2)-bridging ligands, link neighbouring Ni(II) ions into a chain structure along the c axis. These polymeric chains are extended into a three-dimensional framework via inter-molecular O-H?O hydrogen bonds with participation of the water mol-ecules.

Project description:The environment of the Co(II) ion in the title compound, [Co(SO(4))(C(6)H(7)N)(2)(H(2)O)(2)](n), exhibits an octa-hedral configuration with the two 3-methyl-pyridine ligands lying in cis positions with respect to each other and trans to the two coordinated water mol-ecules. The axial positions are occupied by O atoms of the sulfate ions. Co and S atoms occupy special positions (twofold axis, Wyckoff position 4c). Neighboring Co(II) ions are covalently connected with each other through the sulfate ions, thus creating infinite polymeric chains that run along the c axis. The water mol-ecules are connected with neighboring sulfate ions through strong O-H?O hydrogen bonds. Intra-molecular hydrogen bonds parallel to the propagation direction of the chains stabilize the polymeric chains, and inter-molecular hydrogen bonds between chains connect neighboring chains with each other, thus leading to polymeric double chains.
