Abstract

Equimolar reactions between organotin(IV) precursors of SnClxR4-x (R = Bu, Ph, x = 1, 4) and aminoguanidine bicarbonate in methanol has afforded 2:1 and 1:1 (M:L) carbonate complexes as well as 1:2 semicarbazide derivative. The products were characterised by spectroscopic methods such as multinuclear NMR (H-1, C-13 and Sn-119), Myssbauer and infrared spectroscopy as well as microanalysis and melting point. The butyl and phenyl derivatives have a 4- and 5-coordinated metal centre respectively with bridging-bidentate and bridging-tridentate carbonate. For the tetrahalide metal precursor, a 6-coordinated tin(IV) derivative has been achieved with a bidentate semicarbazide towards the metal centre.
