Tris(morpholinium) hexa-μ3-hydroxido-hexa-μ2-oxido-dodecaoxidohexamolybdenum(VI)chromate(III) tetrahydrate

Abstract

In the title organic–inorganic hybrid compound, (C4H10NO)3[H6CrMo6O24]·4H2O, the Anderson-type [H6CrMo6O24]3− polyoxoanion is centrosymmetric, with the CrIII ion lying on an inversion center. One of the two crystallographiclly independent morpholinium cations is half-occupied. Intermolecular N—H...O and O—H...O hydrogen bonds link the cations, polyoxoanions and uncoordinated water molecules.
