Dimanganese(II) hydroxide vanadate, Mn₂(OH)[VO₄]

Dimanganese(II) hydroxide vanadate was obtained from hydro­thermal reactions. The crystal structure of the title compound is isotypic with that of Zn₂(OH)[VO₄]. Three crystallographically independent Mn²⁺ ions are present, one (site symmetry .m.) with a distorted trigonal-bipyramidal and two (site symmetries .m. and 1) with distorted octa­hedral coordination spheres. These polyhedra are linked through common edges, forming a corrugated layer-type of structure extending parallel to (100). A three-dimensional framework results via additional Mn—O—V—O—Mn connectivities involving the two different tetra­hedral [VO₄] units (each with point-group symmetry .m.). O—H...O hydrogen bonds (one bifurcated) between the OH functions (both with point-group symmetry .m.) and the [VO₄] units complete this arrangement.
