| Abstract: | The phenolic azide bridged dinuclear nickel(II) complex, Ni2(L1)2(N3)(H2O)(μ1,1-N3)] · EtOH (I), and the thiocyanate bridged dinuclear copper(II) complex, Cu2(L2)2(μ1,1-NCS)2] (II), where L1 and L2 are the deprotonated forms of 2-mothoxy-6-(2-piperidin-1-ylethylimino)methyl]phenol and 2,4-dichloro-6-(2-methylaminoethylimino)methyl]phenol, respectively, were synthesized and characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. The crystal of I is orthorhombic: space group Pbca, a = 12.172(1), b = 20.953(1), c = 29.779(2) Å, V = 7594.8(9) Å3, Z = 8. The crystal of II is monoclinic: space group P21/n, a = 8.7615(11), b = 19.672(2), c = 16.568(2) Å, β = 99.449(2)°, V = 2816.9(6) Å3, Z = 4. The Ni atoms in I are in octahedral coordinations, and the Cu atoms in II are in square-pyramidal coordinations. |
