The first metal substituted stannatrane, Os(Sn- [OCH2CH2]3N)(η2-S2CNMe2)(CO)(PPh3)2, has been synthesised by reaction between triethanolamine and the triiodostannyl osmium complex Os(SnI3)(η2-S2CNMe2)(CO)(PPh3)2: the transannular SnâN distance of 2.422(4) Ã
indicates a bonding interaction which is not seen in the corresponding silatranyl complex Os(Si[OCH2CH2]3N)- (η2-S2CNMe2)(CO)(PPh3)2 which has an SiâN distance of 3.176(6) Ã
.
通过
三乙醇胺与三
碘锡锇络合物 Os(SnI3)(δ-2-S2CNMe2)(CO)(PPh3)2 的反应,合成了第一种
金属取代的
锡铂络合物 Os(Sn-[OCH2CH2]3N)(δ-2-S2CNMe2)(CO)(PPh3)2。422(4) Ã 表明存在键合作用,而相应的
硅烷基络合物 Os(Si[OCH2CH2]3N)-(δ-2-S2CNMe2)(CO)(PPh3)2 中则没有这种作用,其 SiâN 间距为 3.176(6) Ã。
