Effects of some neutral ligands on the co-ordination of the thiocyanate ion in some anionic platinum(II) complexes
Abstract
The isomers present in solutions of [Pt(CNS)3L]–[L = NMe3, PMe(3 –n)Etn(n= 0–3), AsMe3, AsMe2Et, SbMe3, SMe2, SeMe2, or TeMe2] have been identified by means of 1H-{195Pt} and 31P n.m.r. spectroscopy. N-Bonding of the thiocyanate ion is favoured when L contains a light donor atom, when the trans ligand has a high trans influence, or when a cis ligand is bulky.
