Reinvestigation of MnSn2

Abstract

The structure of manganese distannite, MnSn2, known from X-ray powder diffraction data, has been refined based on single-crystal data. This inter­metallic compound crystallizes in the tetra­gonal CuAl2 structure type. Mn atoms (4a position) form chains parallel to the c axis and each Mn atom is surrounded by eight Sn atoms in a square anti­prism. Each Sn atom (8h position) has four Mn near neighbors from two neighboring Mn chains forming Mn4Sn recta­ngular prisms.
