Abstract
The new compounds LaZn0,52Sb2, LaCo0,68Sb2, LaMnxSb2 (0.65 ≤ x ≤ 0.76) and LaCuxSb2 (0.82 ≤x≤ 0.87) crystallize in the tetragonal system , space group P4/nmm (N o. 129) with the CaMnBi2 structure. The lattice constants are: LaZn0,52Sb2: a = 438.0(3) pm, c = 1048.8(5) pm, c/a = 2.395; LaCo0,68Sb2: a = 439.4(3) pm, c = 995.4(5) pm, c/a = 2.265; LaMnxSb2: für x = 0.65: a = 438.7(3) pm, c = 1078.0(5) pm, c/a = 2.457; für x = 0.76: a = 437.2(3) pm, c = 1093.3(5) pm, c/a = 2.501; LaCuxSb2: für x = 0.82: a = 440.2(3) pm, c = 1015.4(5) pm, c/a = 2.307; für x = 0.87; a = 437.3(3) pm, c = 1040.0(5) pm, c/a = 2.378.Keywords
