A one-dimensional ladder-like coordination polymer derived from chains formed via hydrogen bonds: catena-poly[[aquadipyridinenickel(II)]-mu-2,2'-dithiodibenzoato-kappa3O,O':O"].

ABSTRACT

The title one-dimensional chain nickel(II)-disulfide complex, [Ni(C14H8O4S2)(C5H5N)2(H2O)]n, has each Ni(II) cation coordinated by two N atoms from two pyridine ligands, three carboxylate O atoms from two different dithiodibenzoate ligands and one O atom from a coordinated water molecule, in a distorted octahedral coordination geometry. Each dithiodibenzoate ion links two Ni(II) cations through its carboxylate O atoms, making the structure polymeric. Hydrogen-bond interactions between two shoulder-to-shoulder chains lead to the formation of a ladder-like structure.
