The material described by HoCuPb crystallizes in the hexagonal P6_3mc space group. Ho(1) is bonded in a 9-coordinate geometry to three equivalent Cu(1) and six equivalent Pb(1) atoms. Cu(1) is bonded in a 7-coordinate geometry to three equivalent Ho(1) and four equivalent Pb(1) atoms. Pb(1) is bonded in a 10-coordinate geometry to six equivalent Ho(1) and four equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
