摘要
The reaction of Pt2Ru4(CO)(18) (1) with o-bis(phenylethynyl)benzene (2) has yielded the product Pt2Ru4(CO)(14)[mu(5)-C6H4(C2Ph2)(2)] (3) which exhibits an unexpected 'raft' structure for the six metal atoms. Both alkyne groups are coordinated to the same side of the cluster as triple bridges across neighboring PtRu2 triangles. Compound 3 has two valence electrons less than the 90 electron configuration usually observed for raft clusters. (C) 1999 Elsevier Science S.A. All rights reserved.
