Four new organotin complexes based on m - phthaloyl bis(substituted salicylaldehyde acylhydrazone) (H4L), (SnR2)(2)L (1-4), were synthesized by solvothermal reaction of H4L with (R3SnOH)-Sn-2, or one-pot solvothermal reaction of m - phthaloyl hydrazide, 3 - tert - butyl salicylaldehyde, and tricyclohexyltin hydroxide, where H4L=m - Ph (CONH-N=CH(o-OH)PhR1)(2); R-1= NEt2, R-2=Ph (1); R-1=3,5-di-tert-butyl=3,5-t-2Bu, R-2=Ph (2); R-1=3,5-t-2Bu, R-2=Cy (3); R-1=3-tert-butyl=3-t-Bu, R-2=Cy (4). And they were characterized by elemental analysis, IR, and (H-1, C-13, and Sn-119) NMR. The structures of...
