s,s'-N,N' bridging and s,s-N,N chelating a-diimines. Molecular geometries of[PtCl2PBu3]2 (t-BuN=CHCH=NBu-t) and PtCl2 (styrene)(t-BuN=CHCH=NBu-t)

Abstract

X-ray structure analysis of [PtCl{2}PBu{3}]{2}(t-BuN@?CHCH@?NBu-t) has shown the presence of @s, @s'-N,N'-bonded diimine, which bridges in the anticonfiguration two planar trans-PtCl{2}PBu{3}N moieties. The crystal structure of PtCl{2}(styrene)(t-BuN@?CHCH@?NBu-t) contains a unidentate-bonded styrene molecule in the equatorial position of a trigonal bipyramidal arrangement with the phenyl ring bent back by 27}o{.
