Ligand exchange reactions of bis(cyclo-octa-1,5-diene)platinum; synthesis of trisethyleneplatinum and molecular structure of tris-µ-(t-butyl isocyanide)-tris-(t-butyl isocyanide)-triangulo-triplatinum, [Pt3(ButNC)6]

Abstract
The reaction of [Pt(1,5-C8H12)2] with ButNC yields [Pt3(ButNC)6], structurally identified by X-ray crystallography, and with tricyclohexylphosphine and ethylene affords [Pt(PCy3)2] and [Pt(C2H4)3] respectively (Cy = cyclohexyl); the 14-electron phosphine complex reacts with hydrogen to give trans-[PtH2(PCy3)2].
