The material described by Ho(ReFe5)2 crystallizes in the orthorhombic Immm space group. Ho(1) is bonded in a 20-coordinate geometry to two equivalent Re(1), two equivalent Fe(4), four equivalent Fe(2), four equivalent Fe(3), and eight equivalent Fe(1) atoms. Re(1) is bonded in a 14-coordinate geometry to one Ho(1), one Re(1), two equivalent Fe(2), two equivalent Fe(3), four equivalent Fe(1), and four equivalent Fe(4) atoms. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent Ho(1), two equivalent Re(1), two equivalent Fe(1), two equivalent Fe(2), two equivalent Fe(3), and two equivalent Fe(4) atoms to form a mixture of face, corner, and edge-sharing FeHo2Fe8Re2 cuboctahedra. In the second Fe site, Fe(2) is bonded to two equivalent Ho(1), two equivalent Re(1), two equivalent Fe(3), two equivalent Fe(4), and four equivalent Fe(1) atoms to form a mixture of distorted face, corner, and edge-sharing FeHo2Fe8Re2 cuboctahedra. In the third Fe site, Fe(3) is bonded to two equivalent Ho(1), two equivalent Re(1), two equivalent Fe(2), two equivalent Fe(4), and four equivalent Fe(1) atoms to form a mixture of distorted face, corner, and edge-sharing FeHo2Fe8Re2 cuboctahedra. In the fourth Fe site, Fe(4) is bonded in a 14-coordinate geometry to one Ho(1), four equivalent Re(1), one Fe(4), two equivalent Fe(2), two equivalent Fe(3), and four equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
