Unprecedented nitrosyl-bridged double-A-frame triplatinum complexes, [Pt3(µ-triphosphine)2(µ-NO)2(RNC)2](BF4)4
Abstract
Reaction of linear triplatinum complexes, linear-[Pt3(µ-dpmp)2(RNC)2](PF6)2 1, with an excess of [NO][BF4] afforded an unprecedented nitrosyl-bridged double-A-frame triplatinum complexes, [Pt3(µ-dpmp)2(µ-NO)2(RNC)2](BF4)4 [2a: R = 2,6-xylyl; 2b: R = 2,4,6-mesityl, dpmp = bis(diphenylphosphinomethyl)phenylphosphine], which were characterized by X-ray crystallographic analysis and extended Hückel MO calculations.
