Nd(CoP3)4 crystallizes in the cubic Im-3 space group. Nd(1) is bonded to twelve equivalent P(1) atoms to form NdP12 cuboctahedra that share faces with eight equivalent Co(1)P6 octahedra. Co(1) is bonded to six equivalent P(1) atoms to form CoP6 octahedra that share corners with six equivalent Co(1)P6 octahedra and faces with two equivalent Nd(1)P12 cuboctahedra. The corner-sharing octahedral tilt angles are 60°. P(1) is bonded in a 5-coordinate geometry to one Nd(1), two equivalent Co(1), and two equivalent P(1) atoms.
