title: Dimanganese(II) hydroxide vanadate, Mn2(OH)[VO4].
abstract: Dimanganese(II) hydroxide vanadate was obtained from hydro-thermal reactions. The crystal structure of the title compound is isotypic with that of Zn2(OH)[VO4]. Three crystallographically independent Mn(2+) ions are present, one (site symmetry .m.) with a distorted trigonal-bipyramidal and two (site symmetries .m. and 1) with distorted octa-hedral 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 tetra-hedral [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.
