Four new organotin complexes based on m - phthaloyl bis(substituted salicylaldehyde acylhydrazone) (H4L), (SnR2)2L (1-4), were synthesized by solvothermal reaction of H4L with R23SnOH, 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; R1=NEt2, R2=Ph (1); R1=3,5-di-tert-butyl=3,5-t-2Bu, R2=Ph (2); R1=3,5-t-2Bu, R2= Cy (3); R1=3-tert-butyl=3-t-Bu, R2=Cy (4). And they were characterized by elemental analysis, IR, and (1H, 13C, an...
