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.
[Pt(CNS)3 L] – [L = NMe 3,PMe (3- n) Et n(n = 0-3),AsMe 3,AsMe 2 Et,SbMe 3,SMe 2, SeMe 2或TeMe 2 ]已通过1 H- 195 Pt}和31 P nmr光谱进行了鉴定。Ñ当L中含有一个光供体原子,当所述
硫氰酸根离子的η-键接是有利的反
配体具有高的反式的影响,或者当顺式
配体庞大。
