Synthesis, structures and properties of the catalytic bromination reaction of a series of novel scorperate oxidovanadium complexes with the potential detection of hydrogen peroxide in water

Four scorpionate oxovanadium (IV) complexes: [VO(Tp4I)(pz)(SCN)]·1/2CH2Cl2 (1), [VO(Tp)(pzTp)]·2H2O (2), [VO(Bp)(Tp4I)] (3) and [VO(C5H7O2)(Tp4I)]·CH3OH (4) (Bp: [H2B(pz)[2-]];Tp: [HB(pz)3−];Tp[4I]: [HB(4I-pz)3−];pzTp: [B(pz)4−]) have been synthesized and characterized by elemental analysis, IR, UV-Vis spectroscopy, powder X-ray diffraction, single-crystal X-ray diffraction and thermal gravimetric analyses (TG).
