The crystal structure described by Ho3SmNi4 crystallizes in the monoclinic Pm space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 7-coordinate geometry to one Ni(1), two equivalent Ni(2), two equivalent Ni(3), and two equivalent Ni(4) atoms. In the second Ho site, Ho(2) is bonded in a 7-coordinate geometry to one Ni(4), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Ni(3) atoms. In the third Ho site, Ho(3) is bonded in a 7-coordinate geometry to one Ni(3), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Ni(4) atoms. Sm(1) is bonded in a 7-coordinate geometry to one Ni(2), two equivalent Ni(1), two equivalent Ni(3), and two equivalent Ni(4) atoms. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to one Ho(1), two equivalent Ho(2), two equivalent Ho(3), two equivalent Sm(1), and two equivalent Ni(3) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), two equivalent Ho(3), one Sm(1), and two equivalent Ni(4) atoms. In the third Ni site, Ni(3) is bonded in a 9-coordinate geometry to one Ho(3), two equivalent Ho(1), two equivalent Ho(2), two equivalent Sm(1), and two equivalent Ni(1) atoms. In the fourth Ni site, Ni(4) is bonded in a 9-coordinate geometry to one Ho(2), two equivalent Ho(1), two equivalent Ho(3), two equivalent Sm(1), and two equivalent Ni(2) atoms. is represented by the CIF card [CIF]
