S. Frenzen et H. Mullerbuschbaum, ON A 9L-PEROVSKITE OF THE COMPOSITION BA9 RU3.2MN5.8O27, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 50(4), 1995, pp. 585-588
Single crystals of Ba9Ru3.2Mn5.8O27 have been prepared by flux techniq
ues. X-raf four circle diffractometer measurements led to trigonal (rh
ombohedral) symmetry, space group D-3d(5)-R (3) over bar m, n = 5.7043
(5), c = 21.255(4) Angstrom, Z = 1. This phase is isotypic to BaRuO3.
The crystal structure and the occupation of the M(3)O(12) triple octah
edra bSi ruthenium and manganese are discussed with respect to other o
xides containing M(3)O(12) groups in an ordered and disordered way.
