Five bis(substituted salicylaldehyde) m-phthaloylhydrazone organotin complexes, m-Ph(CONH-N=CH (o-O)PhR1)(SnR2)(2), were synthesized by one-pot solvothermal reaction of benzene-1,3-dicarbohydrazide, substituted salicylaldehydes and organotin precursors, respectively, where R-1=Naphth, R-2=Cy (1); R-1=3-t-Bu, R-2=n-Bu (2); R-1= 5-F, R-2=Ph (3); R-1=4-Cl, R-2=Ph (4); R-1=3-t-Bu, R-2=Ph (5). Their structures were characterized by elemental analysis, IR and H-1, C-13, Sn-119 NMR, and the crystal structures of complexes 1 -5 were confirmed by X-ray diffraction. Complexes 1-4 belong to the triclinic...
