In the second Co site, Co(2) is bonded to one Yb(2), two equivalent Yb(1), two equivalent P(1), and two equivalent P(2) atoms to form distorted CoYb3P4 tetrahedra that share corners with four equivalent Co(4)Yb3P4 tetrahedra, corners with four equivalent Co(1)YbP4 tetrahedra, corners with six equivalent Co(2)Yb3P4 tetrahedra,  an edgeedge with one Co(1)YbP4 tetrahedra, edges with two equivalent Co(2)Yb3P4 tetrahedra, edges with four equivalent Co(4)Yb3P4 tetrahedra,  a faceface with one Co(1)YbP4 tetrahedra, faces with two equivalent Co(2)Yb3P4 tetrahedra, and faces with two equivalent Co(4)Yb3P4 tetrahedra. In the third Co site, Co(3) is bonded in a 5-coordinate geometry to one P(2), two equivalent P(1), and two equivalent P(3) atoms. In the fourth Co site, Co(4) is bonded to one Yb(1), two equivalent Yb(2), two equivalent P(1), and two equivalent P(2) atoms to form distorted CoYb3P4 tetrahedra that share corners with two equivalent Co(1)YbP4 tetrahedra, corners with four equivalent Co(2)Yb3P4 tetrahedra, corners with six equivalent Co(4)Yb3P4 tetrahedra, edges with two equivalent Co(4)Yb3P4 tetrahedra, edges with two equivalent Co(1)YbP4 tetrahedra, edges with four equivalent Co(2)Yb3P4 tetrahedra, faces with two equivalent Co(2)Yb3P4 tetrahedra, faces with two equivalent Co(4)Yb3P4 tetrahedra, and faces with two equivalent Co(1)YbP4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to two equivalent Yb(1), one Co(1), two equivalent Co(2), two equivalent Co(3), and two equivalent Co(4) atoms. In the second P site, P(2) is bonded in a 9-coordinate geometry to two equivalent Yb(2), one Co(3), two equivalent Co(1), two equivalent Co(2), and two equivalent Co(4) atoms. In the third P site, P(3) is bonded in a 9-coordinate geometry to three equivalent Co(1) and six equivalent Co(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
