Synthesis and structural characterization of mono- and dinuclear Mo(V)-oxo-complexes containing bis(3,5-dimethylpyrazol-1-yl)acetate anion as ligand

► Synthesis of Mo(V) complexes with N,N,O-scorpionate ligand Hbdmpza. ► Complexes: [MoOCl2(bdmpza)] [MoOBr2(bdmpza)]∙CH3CN, and [Mo2O4(bdmpza)2]∙2H2O. ► X-ray crystal structure analysis, IR and UV-Vis spectra of complexes.
