ABSTRACT In the title compound, [Nb(CH3O)3(C5H7O2)Cl], the NbV atom is coordinated by two O atoms from the chelating acetylacetonate ligand, three O atoms from the methanolate groups and one chloride ligand. The octahedral environment around niobium is slightly distorted with Nb—O distances in the range 1.8603 (15)–2.1083 (15) Å and an Nb—Cl distance of 2.4693 (9) Å. The O—Nb—O angles vary between 80.74 (6) and 100.82 (7)°, while the trans Cl—Nb—O angle is 167.60 (5)°. There are no hydrogen bonds observed, only an intermolecular C—H...O interaction.
