The Construction of (N2S2)Ni-Pd Clusters: A Slant-Chair, a Basket and a C4-Paddlewheel Structure
Additional Document Info
In pursuit of an analogy between bidentate diphosphane ligands and cis-dithiolato nickel complexes, the easily prepared [bis (mercaptoethane)diazacycloheptane]nickel complex, Ni-1, has been treated with PdII and NiII sources. With the latter, trinickel species are observed with typical slant-chair structures; for palladium(ii) chloride, a basket-type structure is realized in which the floor of the basket is a PdS4 unit and the sides are N2S2 units. One chloride atom is held within the basket at a PdCl distance of 3.26 . With Pd(NO3)2 as a palladium source, a hexanuclear aggregate in the form of a C4-paddlewheel structure is obtained. In this structure, the N2S2Ni complex serves as a bidentate ligand which bridges two Pd2+ cations at a distance of 3.132 . Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
