title: Racemic cis-methoxobis(2-methyl-3-oxo-4H-pyran-4-olato)oxovanadium(V) redetermined at 120 K: hydrogen-bonded ribbons containing R2/2(7), R2/2(14) and R4/4(18) rings.
abstract: In the title compound, [V(CH3O)(C6H5O3)2O], the V-O bond lengths to the oxo and methoxo ligands are 1.593 (3) and 1.768 (3) A, respectively, at 120 K; the V-O bond lengths trans to these two ligands are 2.246 (3) and 2.116 (3) A. Molecules are linked by three C-H...O hydrogen bonds into complex ribbons containing three types of ring.
