Abstract

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 Pd^II^ and Ni^II^ 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 PdS~4~ unit and the sides are N~2~S~2~ units. One chloride atom is held within the basket at a Pd···Cl distance of 3.26 Å. With Pd(NO~3~)~2~ as a palladium source, a hexanuclear aggregate in the form of a C~4~‐paddlewheel structure is obtained. In this structure, the N~2~S~2~Ni complex serves as a bidentate ligand which bridges two Pd^2+^ cations at a distance of 3.132 Å. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
