Tin complexes Sn(NS)2Cl2(D) and Sn(NS)4(E) (NS is monoanionic S-methyl isopropylidenehydrazinecarbodithioate) are very good transmetalators of tetranuclear copper(I) target [NCuCl]4 (I: N is N,N-diethylnicotinamide). An X-ray crystallographic study shows that D is cis-dichloro-bis(trans-S-methyl isopropylidenehydrazinecarbodithioato)tin(IV). Evidence that I reacts with 1 or 2 mol of D via strong precursors D·I and D2·I that contain NS ligands bridging tin to copper is used to discuss the transmetalation sequence. The tin-containing transmetalation products include the remarkable air-stable copper(I)-tin(IV) complex N3Cu2Sn(NS)2Cl4 obtained from the reaction of I with equimolar E.
