Abstract:

The three title complexes containing L (HL = N-phenylpicoloylhydrazide) have been synthesized and characterized. They are VO2L (1, C13H10N3O4V, M-r = 323.18), [NiL2] . 0.5CH(3)OH (2, C26.5H22N6NiO4.5, M-r = 555.21) and [MnL2] . 0.5CH(3)OH (3, C26.5H22MnN6O4.5, M-r=551.44). The complex 1 belongs to triclinic system, space group P (1) over bar, with cell parameters: a = 0.71241(3) nm, b = 0.89625(6) nm, c = 1.1706(6) nm, alpha = 94.715(2)degrees, beta = 102.053(2)degrees, gamma = 112.375(3)degrees, V = 0.63461(7) nm(3), Z = 2, D-c = 1.691Mg . m(-3), F(000) = 328, mu(MoKalpha) = 0.802mm(-1), R = 0.0290 and wR = 0.0816 for 2545 [I greater than or equal to 2sigma(I)] observed reflections, GOF = 1.064. The complex 2 belongs to monoclinic system, space group C2/c, a = 2.5875(1) nm, b = 1.4868 (1) nm, c = 1.8353(1) nm, beta = 134.470(4)degrees, V = 5.2081(5) nm(3), Z = 8, D-c = 1.457Mg . m(-3), F(000) = 2368, mu(MoKalpha) = 0.795mm(-1), R = 0.0459 and wR = 0.1330 for 4144 [I greater than or equal to 2sigma(I)] observed reflections, GOF = 1.029. The complex 3 belongs to monoclinic system, space group C2/c, a = 2.60113 (3) nm, b 1.45231(4) nm, c=1.92903(1) nm, beta=132.824(1)degrees, V=5.3448(2) nm(3), Z = 8, D-c = 1.410Mg . m(-3), F(000) = 2344, mu(MoKalpha) = 0.543mm(-1), R = 0.0457, and wR = 0.1325 for 4079 [I greater than or equal to 2sigma(I)] observed reflections, GOF = 1.055. The vanadium atom in the dioxovanadium complex I has a distorted square pyramidal geometry with VO2(NNO) coordination, the basal plane being two nitrogen donors and one oxygen donor in L and one oxo oxygen atom. Every two molecules related by centrosymmetric operation in 1 are linked by pairs through the intermolecular hydrogen bonds. The nickel atom in the complex 2 and manganese atom in the complex 3 are in a distorted octahedral environment with Ni(NNO) (NNO) and Mn(NNO) (NNO) coordination models, respectively. The one-dimensional structures in 2 and 3 are formed through the intermolecular hydrogen bonds, respectively. In three title complexes, v (C = O) and v (C-N) are shifted to lower frequencies in IR spectra; pi-pi* charge transitions and d-pi* charge-transitions are observed in their electronic spectra.
