A novel cobalt complex, [Co(bdpm)(OBz)](ClO4) (bdpm = bis(3,5-dimethyl-1-pyrazolyl) methane, OBz = benzoate), was synthesized and characterized by elemental analysis, UV-Vis, IR spectroscopy and X-ray diffraction. The complex crystallizes in the trigonal system, space group P3121 with a = 19.2583(9), b = 19.2583(9), c = 25.5269(17) A and gamma = 120 graduate. The complex can catalyze the selective oxidation of alkanes to corresponding alcohols and ketones, and a presumptive mechanism was proposed.
