The compound described by YHgB is half-Heusler structured and crystallizes in the cubic F-43m space group. Y(1) is bonded to six equivalent Hg(1) and four equivalent B(1) atoms to form a mixture of distorted corner and face-sharing YHg6B4 tetrahedra. Hg(1) is bonded in a distorted q6 geometry to six equivalent Y(1) and four equivalent B(1) atoms. B(1) is bonded in a body-centered cubic geometry to four equivalent Y(1) and four equivalent Hg(1) atoms. is represented by the CIF file [CIF]
