The material described by HoTiGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ho(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. Ti(1) is bonded to four equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing TiGe4 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Ho(1) and four equivalent Ti(1) atoms. is represented by the CIF card [CIF]
