A cis-Dioxomolybdenum(VI) Complex, [Mo{N₂C₃H₃C(Me)₂O}₂(O)₂]

In the cis-dioxomolybdenum(VI) complex bis[1-methyl-1-(1-pyrazolyl)ethanolato-N²,O]dioxomolybdenum(VI), [Mo(O)₂(C₆H₉N₂O)₂] or C₁₂H₁₈MoN₄O₄, the Mo atom has distorted octahedral coordination to two (cis) oxo ligands and two N and two O atoms of the two substituted pyrazole ligands. Mo-O_oxo bond distances [mean 1.698 (6) Å] correspond to double bonds, Mo-O_oxy [mean 1.951 (2) Å] to single bonds, and Mo-N bonds [mean 2.326 (3) Å] are lengthened as a result of the effect of the oxo ligands, which are trans to the N atoms.
