Two Cd(II) complexes, Cd2L2Cl2(1) and Cd2L2(NCS)2(2)(HL = N-(3-methoxyl-salicylidene)-3-dimethylaminopropylamine) were synthesized and determined by EA, IR, TG and single-crystal X-ray diffraction.The crystallographic data are as follows:monoclinic, space group P21/n, a = 9.2710(9), b = 18.0069(18), c = 18.5562(19) , β = 99.741(4)o, V = 3053.1(5), Z = 4, μ = 1.605, F(000) = 1536, R = 0.0264 and wR = 0.0699 for 1;orthorhombic, space group Pca21, a = 16.196(3), b = 11.506(2), c = 36.126(7), V = 6732(2), Z = 8, μ = 1.428, F(000) = 3264, R = 0.0376 and wR = 0.0877 for 2.There are two geometrically different octahedral Cd(II) atoms, with N4O2 and O4Cl2 donor sets for 1 while N4O2 and N2O4 for 2.In the dinuclear Cd(II) centers, the Cd(II) atoms are held together by two deprotonted phenolate oxygen atoms from tetradentate L-ligands.The thermal gravity data show two step decompositions with the residues of CdO for two complexes.
Two complexes of Cd (II) complexes, Cd2L2Cl2 (1) and Cd2L2 (NCS) 2 (HL = N- (3-methoxyl-salicylidene) -3-dimethylaminopropylamine) were synthesized and determined by EA, IR, TG and single- Crystal X-ray diffraction. The crystallographic data are as follows: monoclinic, space group P21 / n, a = 9.2710 (9), b = 18.0069 (18), c = 18.5562 (19) , V = 3053.1 (5), Z = 4, μ = 1.605, F (000) = 1536, R = 0.0264 and wR = 0.0699 for 1; orthorhombic space group Pca21, a = 16.196 (3), b = 11.506 (2), c = 36.126 (7) , V = 6732 (2), Z = 8, μ = 1.428, F (000) = 3264, R = 0.0376 and wR = 0.0877 for 2. Both are two geometrically different octahedral Cd (II) atoms, with N4O2 and O4Cl2 donor sets for 1 while N4O2 and N2O4 for 2.In the dinuclear Cd (II) centers, the Cd (II) atoms are held together by two deprotonated phenolate oxygen atoms from tetradentate L-ligands. The thermal gravity data show two step decompositions with the residues of CdO for two complexes.
