摘要:
The coordination around the nickel ions in the title complex, [Ni-3(C17H16N2O2)(2)(C2H3O2)(2){(CH3)(2)SO}(2)], is irregular octahedral. The central nickel ion occupying the inversion centre has four O atoms from two N,N'-bis(salicylidene)1,3-propanediaminato (SALPD(2-)) ligands and one O atom from each bridging acetate group. The average Ni-O distance for the central Ni ion is 2.072(2) Angstrom. The coordination around the terminal Ni ions, related by an inversion centre, comprises two O atoms and two N atoms from a SALPD(2-) ligand as well as one O-acetate and one O-DMSO atom. The DMSO and acetate ligands are trans about the terminal Ni atom. The average Ni-O and Ni-N distances for the terminal Ni ions are 2.087 (2) and 2.018 (3) Angstrom, respectively. The Ni ... Ni bridging distance is 3.043 (2) Angstrom.
