Crystal structure of BaMnB₂O₅ containing structurally isolated manganese oxide sheets.

ABSTRACT: In an attempt to search for mixed alkaline-earth and transition metal pyroborates, the title compound, barium manganese(II) pyroborate, has been synthesized by employing a flux method. The structure of BaMnB₂O₅ is composed of MnO₅ square pyramids that form Mn₂O₈ dimers by edge-sharing and of pyroborate units ([B₂O₅]^4-) that are composed of two corner-sharing trigonal-planar BO₃ units. These building blocks share corners to form _∞²[MnB₂O₅]^2- layers extending parallel to (100). The Ba²⁺ cations reside in the gap between two manganese pyroborate slabs with a coordination number of nine. The title compound forms an inter-esting spi
