Reaction of the dimeric dimethyltin(IV)cupferronato complex [Me 2 Sn(O 2 N 2 Ph) 2 ] 2 ( 1 ) with 4,4′‐bipyridine (bipy), pyridine (py), and 2,6‐diamino‐4‐phenyl‐1,3,5‐triazine (dpt) afforded three new hepta‐coordinated derivatives, [µ‐(4,4′‐bipy){Me 2 Sn(O 2 N 2 Ph) 2 } 2 ]·MeOH ( 2 ), Me 2 Sn(O 2 N 2 Ph) 2 (py) ( 3 ), and [Me 2 Sn(O 2 N 2 Ph) 2 (MeOH)]·dpt ( 4 ). These were characterised by X‐ray structural analysis and solid‐state 119 Sn, 13 C 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 Me 2 Sn IV centre in a nearly symmetrical arrangement. Compound 4 contained supramolecular self‐assembled ribbons, formed by hydrogen bonds between Me 2 SnO 5 moieties and pairs of dpt molecules.
