Formation of trinuclear palladium orthometalated complexes with unprecedented asymmetrical (mu(3)-S)(mu(3)-X) bridges (X = OH, SR, O2CR) from mu(2)-hydroxo dimeric complexes and CS2

摘要

Complexes [Pd-3(mu(3)-S)(mu(3)-X)(L)(3)] (L = orthometalated imine), obtained by an unusual reaction of mu(2)-OH dimeric complexes and CS2, are an unprecedented type of asymmetrical bridges between metallatriangles, which force an all-cis arrangement of the three orthometalated ligands relative to the metallatriangle.
