摘要：
Two new octahedral Cd(II) complexes [Cd(L)(2)] (1) and {[Cd(LH)(2)(SCN)(2)]H2O} (2) [where LH = C14H13N3O] are synthesized using a tridentate hydrazone ligand (LH) and they are characterized by elemental analysis, IR spectra, NMR spectra, thermal studies and finally the structures have been determined by single crystal X-ray diffraction. Complex 1 crystallizes in monoclinic system, space group C2/c with a = 22.565(6) angstrom, b = 10.252(3) angstrom, c = 12.187(4) angstrom, beta = 118.851(2)degrees, and Z = 4. Complex 2 also crystallizes in the monoclinic system, space group P2(1)/c with a = 9.257(9)angstrom, b = 17.809(2)angstrom, c = 9.548(9)angstrom, beta = 107.439(4)degrees, and Z = 2. In 1 the ligand binds the Cd(II) ion in tridentate fashion, whereas in 2 it acts as a bidentate ligand.
