Abstract:

The three title complexes containing L (HL = N-phenylpicoloylhydrazide) have been synthesized and characterized. They are VO2L (1, C 13H10N3O4V, Mr = 323.18), [NiL2] · 0.5 CH3OH (2, C26.5H 22N6NiiO4.5, Mr = 555.21) and [MnL2] · 0.5 CH3OH (3, C26.5H 22MnN6O4.5, Mr = 551.44). The complex 1 belongs to triclinic system, space group P1̄, with cell parameters: a = 0.71241(3) nm, b = 0.89625(6) nm, c = 1.1706(6) nm, α = 94.715(2)°, β = 102.053(2)°, γ = 112.375(3)°, V = 0.63461(7) nm3, Z = 2, Dc = 1.691 Mg · m -3, F(000) = 328, μ(Mo Kα) = 0.802 mm-1, R = 0.0290 and wR = 0.0816 for 2545 [I ≥ 2 σ(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, β = 134.470(4)°, V = 5.2081(5) nm3, Z = 8, Dc = 1.457 Mg · m -3, F(000) = 2368, μ(Mo Kα) = 0.795 mm-1, R = 0.0459 and wR = 0.1330 for 4144 [I ≥ 2 σ(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, β = 132.824(1)°, V = 5.3448(2) nm3, Z = 8, Dc = 1.410 Mg · m -3, F(000) = 2344, μ(Mo Kα) = 0.543 mm-1, R = 0.0457, and wR = 0.1325 for 4079 [I ≥ 2 σ(I)] observed reflections, GOF = 1.055. The vanadium atom in the dioxovanadium complex 1 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 enviromnent 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; π-π* charge transitions and d-π* charge-transitions are observed in their electronic spectra.
