N-(3-hydroxypyridine-2-yl)salicylidineimine (1), N-(3-hydroxypyridine-2-yl)-5-bromo salicylideneimine (2) and their diorganotin(IV) complexes formulated as Me2Sn(OC6H4CH=NC5H3NO) (3) and Me2Sn(OC6H3BrCH=NC5H3NO) (4) were prepared and characterized by H-1-NMR, IR, mass spectroscopy and single crystal x-ray diffraction study. The crystal structures of 3 [orthorhombic, Pbna (no 60); a = 10.439(1) Angstrom, b = 13.388(3) Angstrom, c = 19.340(2) Angstrom, Z = 4; V = 2703(1) Angstrom(3)] and 4 [monoclinic, P2(1)/a (no 14); a = 7.528(4) Angstrom, b = 16.576(7) Angstrom, c = 12.017(7) Angstrom, beta = 97.97(5)degrees, Z = 4; V = 1485(1) Angstrom(3)] have been solved by standard methods and refined by full-matrix least squares (carried out on F-2) to R values of 0.066 and 0.046 respectively. The studied tin(IV) complexes (3 and 4) exhibit the distorted trigonal-bipyramidal geometries around Sn atoms, separately. The tautomeric effects of ligands and the substitution of Br atom to the common molecular structure were discussed beside of the coordination geometries of 3 and 4.
