Synthesis of tris (t-Butylisocyanide) bis (tri-n-butylphosphine)-cobalt (II) Perchlorate. An example of a Cobalt (II) Complex with Alkylisocyanide and Trialkylphosphine Ligands

摘要

A cobalt (II) complex with alkylisocyanide andtrialkylphosphine ligands is reported. Tris- (t-butylisocyanide)bis(tri-n-butylphosphine)cobalt (II) perchlorate,[Co(CNCMe3)3{P(C4H9-n)3}2](ClO4)2, was synthesized byAgClO4 oxidation of [Co(CNCMe3)3{P(C4H9-n)3}2]ClO4.Characterization in solid and solution states indicates that thecoordination structure cannot be the familiar axially-disubstitutedtrigonal bipyramidal coordination seen in Co (II)-triarylphosphinecomplexes A C2v trigonal bipyramidal or square pyramidalstructure is postulated for the solution state
