Summary By reacting 2- and 3-aminobenzoic acids (HL1 and HL2, respectively), as well as 2-, 3- and 4-((E)-2-[4-(dimethylamino)phenyl]diazenyl)benzoic acids (HL3, HL4 and HL5, in this order) with a n-butyltin(IV) source [ n BuSn(O)OH or n Bu2SnO], the drum-type butylstannoxane complexes of general composition [ n Bu6Sn6O6(L n )6] [L n =L1 (1), L2 (2) and L3 (3)] and the ladder-type compounds [ n Bu8Sn4O2(L n )4] [L n =L3 (5), L4 (6) and L5 (7)] were obtained and fully characterized. By reacting 1 with 2-((E)-[4-(dimethylamino)benzylidene]amino)benzoic acid (HL6), a co-crystal (4) was achieved which comprises the metal complex aggregate found in 1 and the neutral HL6 molecule. The solution properties of the compounds were assessed from 1H and 13C NMR studies and, for the metal complexes, also from 119Sn NMR. The molecular structures of 1, 2, 4-7 were confirmed by single-crystal X-ray diffraction. Compounds 1-3 and the complex moiety of 4 display hexameric Sn6O6 clusters with drum-like structures, but 5-7 reveal Sn4O2 cores with ladder-type structural motifs. Besides the observed relationship between the ligand N-functional group and obtained (drum- or ladder-type) assemblies, the relative position of the carboxylate group in the ligand itself influences its coplanarity.
