Synthesis and characteization of new molybdenum(VI)oxalate complexes. Crystal structure of tetramethylammonium salt of μ -oxo-diaquadioxalatotetraoxodimolybdenum(VI)

摘要

In the reaction of molybdenum(VI)oxide with oxalic acid and RCl (R = pyH andγ-picH), new dinuclear complexes of molybdenum(VI) R_2[Mo_2O_5(C_2O_4)_2(H_2O)_2]have been prepared. When molybdenum(VI) Oxide was treated with aqueous solution of tetramethylammonium Oxalate complex,[(CH_3)_4N]_2[MoO_3(C_2O_4)].H_2O was isolated. The Unknown crystal structure of[(CH_3)_4N]_2[Mo_2O_5(C_2O_4)_2]was Determined from single crystal diffractometre data and refined to the Final R value of 0.0317.
