摘要: This review includes over two hundred heterotetranuclear platinum clusters. The clusters are of the compositions Pt3M, Pt3M2, PtM3, Pt′2MM′, PtM2M′ and PtMM′M”. There twenty five different M atoms (transition non-transition) as a partner(s) platinum. four metal found in tetrahedral, planar-rhombohedral, butterfly, spited-triangular, cubane, eight — oligo-membered rings unique structures. is wide variety ligands from uni to- undecadentate, with most common P C donor sites. shortest Pt-M (transition) versus (non-transition) bond distances 2.4833(8)A (M=Pd) vs. 2.4365(5)A (Ge). Several relationships between various structural parameters were discussed. Open image new window
