Abstract
Polycrystalline samples and a single crystal of the Mn sillenite Bi12MnO20 have been synthesized and studied. IR spectroscopy, XANES, and XRPD show that manganese atoms are tetravalent and tetrahedrally coordinated by oxygen. The X-ray single-crystal study of Bi12MnO20 confirms that this is the first example of a compound containing MnIV in tetrahedral coordination by oxygen with Mn-O distances of 1.75(2) Å. The crystal is cubic, sp.gr. I23 (Z = 2); a = 10.206(1) Å. The final agreement factors are wR = 2.83 and R = 3.49% for 625 reflections. Bi12MnO20 belongs to the stoichiometric sillenites with tetravalent M atoms of one kind.
