Bimetallic dioxidovanadium(V) complex containing a malonohydrazide derivative ligand: Synthesis, characterization, and crystal structure

In this paper, we report the synthesis and characterization of dioxidovanadium(V) complex derived from a malonohydrazide ligand (N'1,N'3-bis(2-hydroxybenzylidene) malonohydrazide). The newly synthesized was characterized by infrared spectroscopy (IR), nuclear magnetic resonance (NMR), structure also established single crystal X-ray diffraction study. bimetallic crystallizes in triclinic space group P-1 with following parameters = 10.8273(5) Å, b 11.4677(6) c 15.0366(8) α 81.591(4)°, β 83.018(4)°, γ 76.326(4)°, V 1787.23(16) Å3, Z 2, T 292.5(2) K, μ(MoKα) 0.600 mm-1, Dcalc 1.463 g/cm3, 11730 reflections measured (6.236° ≤ 2Θ 58.062°), 7981 unique (Rint 0.0231, Rsigma 0.0506) which were used all calculations. final R1 0.0496 (I > 2σ(I)) wR2 0.1255 (all data). coordinated to metal ions tridentate fashion through donor O/N/O atoms. adopted square pyramidal geometry slight distortion.
