The system Gd/Co/B: Preparation and characterization by X-ray diffraction of GdCO4B, Gd3CO11B4, GdCoB4, and GdCo12B6

摘要

The compounds GdCo4B, Gd3Co11B4, GdCoB4, and GdCo12B6 were characterized by X-ray investigations of single crystals. GdCo4B (P 6/mmm, a = 505.9(1) pm, c = 690.1 (1) pm) crystallizes with the CeCo4B structure type; Gd3Co11B4 (P 6/mmm, a = 508.7(1) pm, c = 982.9(9) pm) with the Ce3Co11B4 stucture type; GdCo12B6 (R(3) over bar m, a = 949.5(1)pm, c = 747.4(1)pm) with the SrNi12B6 structure type and GdCoB4 (P bam, a = 591.3(9) pm, b = 1145.1(6) pm, c 346.2(3) pm) with the YbCoB4 structure type.
