Cyano-bridged organotin compounds. Crystal structure of a trinuclear dianion containing a nearly linear array of nine atoms
Abstract
The use of PPN+[PPN+=(Ph3P)2N+] instead of K+ as counter-cation for cyanometallate anions, permits variation of the reactivity of the latter species towards electrophilic compounds such as organotin halides; an unusual trinuclear dianion [(Ph3SnCl)2(µ-NC)2Fe(CN)2(dmso)2]2–(dmso = dimethyl sulphoxide) has been obtained in this way, instead of the polymeric material produced by the corresponding potassium cyanoferrate.
