“…Tw oL SÀ ligands are ligated to one octahedral Ni II in am eridional fashion with two thiol Sa nd two imine Nd onors of two ligands in cis and trans positions, respectively (Figure 1, bottom). Theo ther Ni is ligated to three donors of one L SÀ and is bridged via one thiol-S of aL SÀ ligated to first Ni thus adopts as quare planar coordination geometry.T he avg.N i À Na nd Ni À Sd istances found for the octahedral Ni II are 2.064(8) and 2.402(3) ,respectively,and the corresponding distances for the square planar Ni II are 1.902(8) and 2.177(3) ,r espectively.T hese Ni II ÀSd istances are comparable to those of the six [22,27,28] and four-coordinate [19,20,29] Ni II -thiolate complexes with N,Sdonor ligands.…”
