Catena-Poly[[tetra-μ-acetato-κ8O:O′-dinickel(II)]-μ-2,3′-dipyridylamine-κ2N:N′

Abstract

The title complex, [Ni2(C2H3O2)4(C10H7N3)]n or [Ni2(dbp)(C2O2H3)4]n (dbp = 2,3′-dipyridylamine), forms a polymeric linear chain. The repeat unit of the chain is the dinuclear [Ni2(C10H7N3)(C2O2H3)4] of the paddle-wheel type. The two Ni atoms are related by symmetry through an inversion center. Each Ni atom has a square-pyramidal coordination environment, with four O atoms from four acetate groups forming the basal plane, and a pyridyl N atom occupying the apex. The bridging dbp ligand is disordered over an inversion center, involving two alternative positions for the NH group.
