Nine new organotin complexes, namely [SnR2XY(BtzH)2] (1: R = Me, X = Y = Cl, 2: R = Me, X = Y = Br, 3: R = nBu, X = Cl, Y = OH; 4: R = Ph, X = Y = Cl; 5a: R = Me, X = Y = NO3; 5b: R = Me, X = Y = ClO4) and [SnR2X2(5-NO2indH) 2] (6: R = Me, X = Cl; 7: R = nBu, X = Cl; 8: R = Me, X = 5-NO2ind) were obtained by reaction of SnR2X2 with BtzH (1,2,3-benzotriazole) and 5-NO2indH (5-nitroindazole). These compounds were characterized by IR, NMR and ESI MS, and 1 is shown by a single crystal X-ray study to comprise mononuclear centrosymmetric molecules, all pairs of ligands being mutually opposed in a quasi-octahedral coordination sphere. Sn-Cl, C, N are 2.5700(5), 2.108(2), 2.357(2)?. A new triclinic (P1?) polymorph of the binuclear [{tBu2ClSn(μ-OH)} 2], 9 is also described (cf. the earlier monoclinic (P2 1/c)). The unit cell contents comprise a pair of centrosymmetric dimers: Sn-O are 2.042(4)-2.215(4), Sn-Cl 2.489(2), 2.491(2), Sn-C 2.166(6)-2.203(7) ?, O-Sn-O 68.4(2) (x2), and Sn-O-Sn 111.6(2)° (x2).
