Abstract

It was proved by ¹H NOE-difference spectroscopy that all diorganotin(IV) complexes of type R₂Sn(oxin)₂ and R₂Sn(txin)₂ (where oxin = 8-quinolinolate, txin = 8-quinolinethiolate, R = butyl, phenyl, benzyl and vinyl, respectively) in chloroform solution have a distored cis-octahedral coordination at the metal centre. Two oxygen (sulphur) atoms occupy positions trans to each other, while the estimated bond angles OSnO (SSnS) are in the range 150-165°. Nitrogen atoms are cis to each other and the bond angles NSnN are less than 90°. Intramolecular dynamic processes have to be taken into account.
