The reaction of N, N-bis(2-hydroxy-4-R-benzylidene)-1,2-phenylendiimine (1 R = OH, 2 R = OMe) with R'2SnO (R' = Me, n-Bu, Ph) provided six new organotin derivatives: dimethyl-di-n-butyl-and diphenyl [N, N'-bis(3-hydroxysalicylaldehyde)-1,2-phenylenediiminato]tin(IV) (1a), (1b), (1c) as well as dimethyl-di-n-butyl-and diphenyl[N, N'-bis(3-methoxysalicylaldehyde)-1,2-phenylenediiminato]tin(IV), (2a), (2b), (2c), respectively. All compounds were characterized by H-1, C-13 and Sn-119-NMR, elemental analysis, UV, IR, and mass spectrometry. Compounds 2a, 2b and 2c were characterized by single-crystal X-ray structure analysis. In the solid state, 2a, 2b, and 2c showed the Schiff bases backbone in a bent arrangement containing a tin atom with distorted octahedral geometry, where the ligand occupies the four equatorial positions and the methyl, n-butyl, or phenyl groups occupy the trans axial positions. The second-order nonlinear optical response of representative organotin compounds 2a-c was estimated by electric field induced second harmonic (EFISH) measurements where interesting beta(mu) values in the promising range of 10-60 x 10(-30) esu were evaluated.
