Synthesis and crystal structures of a polymeric trimethyltin(IV) and a tetranuclear dibutyltin(IV) complex with azo-carboxylates derived from 4- or 3-amino benzoic acid and naphthalen-1 or 2-ol

Complex 1 was synthesized by the reaction of 4-(4-hydroxynaphthylazo)-benzoic acid with trimethyltin(IV) chloride in anhydrous methanol using triethylamine as base while 2 was synthesized by the re...
