Abstract

Reaction of the dimeric dimethyltin(IV)cupferronato complex [Me2Sn(O2N2Ph)2]2 (1) with 4,4′-bipyridine (bipy), pyridine (py), and 2,6-diamino-4-phenyl-l,3,5-triazine (dpt) afforded three new hepta-coordinated derivatives, [μ-(4,4′-bipy) {Me2Sn(O2N2Ph)2}2 ]·MeOH (2), Me2Sn(O2N2Ph)2(py) (3), and [Me2Sn(O2N2Ph)2(MeOH)]·dpt (4). These were characterised by X-ray structural analysis and solid-state 119Sn, 13C CP MAS NMR-, and multinuclear solution NMR spectroscopy. Single-crystal X-ray diffraction analysis of 2-4 showed that in all three compounds tin was hepta-coordinated, and the cupferronato anions were chelated to the Me2SnIV centre in a nearly symmetrical arrangement. Compound 4 contained supramolecular self-assembled ribbons, formed by hydrogen bonds between Me2SnO5 moieties and pairs of dpt molecules.
