Abstract
The reaction of CoCl2, RuCl3, Na2(mp), and PBun3 (H2mp = 2-mercaptophenol, PBun3 = tri-n-butylphosphine) in ethanol in the molar ratio of 0.75:0.25:1:1 gave the complex Co6Ru2(mp)10(PBun3)6. The heterooctanuclear complex consists of six cobalt and two ruthenium ions chelated to as well as bridged by the 2-mercaptophenol ligands in a near-dimeric fashion with two μ2-OR groups bridging the two Co3Ru(mp)5(PBun3)3 fragments without a crystallographic center of symmetry. Each fragment is formed by binding two of the Co(mp)2(PBun3) structural units and one Co(mp) species to a central Ru(III) ion through the S donors of the five mp ligands, while the sixth coordination site of the octahedral Ru environment is completed by a phosphine ligand in the axial position. The Co6Ru2 moiety exhibits a zigzag assembly constructed by the μ2-O and μ2-S bridges of the bidentate 2-mercaptophenol ligands in a highly asymmetric fashion. The Co atoms are square pyramidally coordinated with apices that are occupied by the phosphin...
