Two 2-oxo-3-phenylpropionic acid arylformylhydrazone dibenzyltin (IV) complexes {[C4H3O(O)C=N-N=C(PhCH2)COOl(C6H5CH2)(2)Sn(CH3OH)}(2) (I) and {[t-Bu-C6H4(O)C=N-N=C(PhCH2)COO](C6H5CH2)(2)Sn(CH3OH)}(2) (II) have been synthesized and characterized by IR, H-1, C-13 and Sn-119 NMR spectra, HRMS, and elemental, thermal stability and single-crystal X-ray diffraction analyses. Complex I crystallizes in the triclinic system, space group P (1) over bar with a = 9.0392(9), b = 10.249(1), c = 15.5762(15) angstrom, alpha = 98.605(1)degrees, beta = 103.765(1)degrees, gamma = 104.056(1)degrees, Z = 2, V = 13...
