The Crystal Structure of Mn₂O₇

Abstract

Mn 2 O 7 —a long‐known compound, whose crystal structure has finally been elucidated: the Mn atoms are surrounded tetrahedrally by O atoms; the bridging and the terminal Mn–O bonds are, as expected, of different lengths. The Mn 2 O 7 molecules are packed in such a way that an only slightly distorted fcc arrangement results for the O atoms.
