Abstract
The structure of TR-fersmite (Ca0.89Ce0.11)(Nb1.3Ti0.7)O-5(O, OH) was refin ed to R = 0.032 The parameters of the orthorhombic unit cell are a = 5.762( 2) Angstrom, b = 14.988(8) Angstrom, c = 5.236(1) Angstrom, sp. gr. Pcan, Z = 4. The mixed A position is occupied by ea and Ce atoms, and the mixed B position is occupied by Nh and Ti atoms. (C) 2001 MAIK "Nauka/Interperiodic a".
