[N'-(3-Eth-oxy-2-oxidobenzyl-idene)-4-hy-droxy-3-meth-oxy-benzohydrazidato](methanol)dioxidomolybdenum(VI).

ABSTRACT: In the title dioxidomolybdenum(VI) complex, [Mo(C(17)H(16)N(2)O(5))O(2)(CH(3)OH)], the Mo(VI) atom is coordinated by the phenolate O, imine N and enolic O atoms of the tridentate hydrazone ligand, one methanol O atom, and two oxide O atoms, forming a distorted octa-hedral coordination geometry. The oxide O atoms adopt a cis conformation: one is trans to the methanol O atom and the other is trans to the ligand N atom. The dihedral angle between the two benzene rings in the hydrazone ligand is 4.0?(3)°. In the crystal, mol-ecules are linked by O-H?N and O-H?O hydrogen bonds.
