Abstract
The structures of LaCr0.6Ni0.4O3 and LaCr0.6Ni0.4O2.8 have been determ ined by Rietveld refinement of neutron powder diffraction data. LaCr0. 6Ni0.4O3 adopts the orthorhombic GdFeO3 structure with space group Pnm a, a = 5.4735(1) Angstrom, b = 7.7568(2) Angstrom, c = 5.5105(1) Angst rom, V = 233.96 Angstrom(3), Z = 4. LaCr0.6Ni0.4O2.8 is rhombohedral, with space group R(3) over barc$, and a = 5.5264(3) Angstrom, c = 13.2 991(4) Angstrom, V = 351.754 Angstrom(3), Z = 6. Copyright (C) 1997 El sevier Science Ltd.
