Crystal structure of calcium lithium plumbide (1/1/1), CaLiPb, and ytterbium lithium plumbide (1/1/1), YbLiPb

Abstract

CaLiPb, hexagonal, P6m2 (No. 187 Source of materialThe title compounds were synthesized starting from the elements (Ca 99.5%, Yb 99.9%, Li 99.9%, Pb 99.999%), by induction melting in tantalum crucibles sealed by arc welding under argon. Experimental detailsA refinement in the space group P3m 1, where the closely related structure of CaLiSn [1] was originally described, was made for both compounds, resulting in slightly higher disagreement factors and standard deviations. DiscussionCaLiPb

“…CaLiPb crystallizes in the hexagonal YbAgPb type structure with space group P6m2 (No. 187)[54]. The crystal structure of CaLiPb is shown as an example in Fig.2(a), in which the three Pb atoms are located at two nonequivalent crystallographic sites: 2h(1/3, 2/3, 0.1533) and 1f (2/3, 1/3, 0.5), thus form three triangular lattices which have the same structure as the prototypical structure.…”
