The material described by GdFe5P3 crystallizes in the orthorhombic Pnma space group. Gd(1) is bonded in a 16-coordinate geometry to one Fe(5), three equivalent Fe(1), three equivalent Fe(2), three equivalent Fe(3), two equivalent P(1), two equivalent P(2), and two equivalent P(3) atoms. There are five inequivalent Fe sites.

In the third Fe site, Fe(3) is bonded to three equivalent Gd(1), one P(1), one P(2), and two equivalent P(3) atoms to form distorted FeGd3P4 tetrahedra that share  a cornercorner with one Fe(5)GdP4 tetrahedra, corners with three equivalent Fe(1)Gd3P4 tetrahedra, corners with four equivalent Fe(3)Gd3P4 tetrahedra, corners with six equivalent Fe(2)Gd3P4 tetrahedra, edges with two equivalent Fe(2)Gd3P4 tetrahedra, edges with two equivalent Fe(3)Gd3P4 tetrahedra, edges with three equivalent Fe(5)GdP4 tetrahedra, faces with two equivalent Fe(2)Gd3P4 tetrahedra, and faces with three equivalent Fe(1)Gd3P4 tetrahedra. In the fourth Fe site, Fe(4) is bonded in a 5-coordinate geometry to one P(3), two equivalent P(1), and two equivalent P(2) atoms. In the fifth Fe site, Fe(5) is bonded to one Gd(1), one P(1), and three equivalent P(2) atoms to form distorted FeGdP4 tetrahedra that share  a cornercorner with one Fe(3)Gd3P4 tetrahedra, corners with two equivalent Fe(1)Gd3P4 tetrahedra, corners with two equivalent Fe(5)GdP4 tetrahedra, corners with four equivalent Fe(2)Gd3P4 tetrahedra, edges with two equivalent Fe(5)GdP4 tetrahedra, edges with three equivalent Fe(3)Gd3P4 tetrahedra, and faces with two equivalent Fe(1)Gd3P4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to two equivalent Gd(1), one Fe(2), one Fe(3), one Fe(5), two equivalent Fe(1), and two equivalent Fe(4) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Gd(1), one Fe(1), one Fe(3), two equivalent Fe(4), and three equivalent Fe(5) atoms. In the third P site, P(3) is bonded in a 9-coordinate geometry to two equivalent Gd(1), one Fe(1), one Fe(4), two equivalent Fe(3), and three equivalent Fe(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
