Snythesis and spectroscopic characterization of some new [tris (3,5-dimethyl-pyrazol) borato] molybdebum complexex

Abstract

In this study, the new binuclear oxo bridged imido Mo(V) complexes [MoTp*(O)Cl](µ-O)[MoTp*(Cl)(≡NC6H4X)], (p-X = Cl, Br) and [MoTp*(O)Cl](µ-O) [MoTp*(Cl)(≡NC6H4Y)], (m-Y = I, F) have been synthesized by the reaction oxo molybdenum (V) precursor [MoTp*(O)Cl2]; [Tp* = Tris(3, 5-dimethyl-pyrazol)borato] with p- and m- functionalized anilines, H2NC6H4X and H2NC6H4Y (p-X = Cl, Br; m-Y=I, F) in toluene solution. The complexes have been characterised by 1 H-NMR, IR spectroscopy and FABMassspectrometry. The structures of [MoTp*(O)Cl](µ-O)[MoTp*(Cl)(≡NC6H4X)], (p-X = Br) and [MoTp*(O)Cl](µ-O)[MoTp*(Cl)(≡NC6H4Y)], (m-Y = I, F) have been characterised by X-Ray diffaction method.
