The reaction of diorganotin(IV) oxides, R2SnO with R = Me, Et, and i-Pr, with nitric acid in different stoichiometric ratios resulted in the formation of different products depending on the organic groups. The diorganotin(IV) nitrate hydroxides Me2Sn(NO3)(OH) (1a) Et2Sn(NO3)(OH), alpha-1b, beta-1b, i-Pr2Sn(NO3)(OH) (1c), the diisopropyltin(IV) dinitrate dihydrate, i-Pr2Sn(NO3)(2)center dot 2H(2)O (2c) and the diisopropyltin(IV) nitrate oxalate dihydrate, [i-Pr2Sn(NO3)](2)Ox center dot 2H(2)O (3) as side-product. On examination of the solubility of the primary reaction products in different solvents, the two additional compounds Me2Sn(NO3)(OH)center dot DMSO (4) and 2i-Pr2Sn(NO3)(2)center dot 3DMSO = [i-Pr2Sn(NO3)(dmso)(3)] [i-Pr2Sn(NO3)(3)] (5) have been isolated. All compounds have been structurally characterized by single crystal X-ray diffraction with special respect to dimensionality (1a, alpha-1b, 1c = dimeric molecules hydrogen bonded to one-dimensional chains; beta-1b = two-dimensional coordination polymer; 2c = monomeric; 3 = monomeric, tin atoms linked via a double side-on chelating oxalate ion; 4 = dimeric, 5 = monomeric anion/cation), tin coordination (trigonal-bipyramidal = 1a, alpha-1b, 1c; six-fold = beta-1b; seven-fold = 3, 4, 5-cation; eight-fold = 2c, 5-anion) and nitrate bonding modes (monodentate = 1a, alpha-1b, 1c; unsymmetrical bidentate = 3, symmetrical bidentate = 3, 4, 5-cation, 5-anion; syn-anti bridging = beta-1b), the latter one being analysed using both, Sn-O and N-O distances.
