La La La Co W
La3WCo crystallizes in the trigonal R3m space group. La(1) is bonded in a 1-coordinate geometry to three equivalent W(1) and one Co(1) atom. There is one shorter (2.88 Å) and two longer (3.78 Å) La(1)-W(1) bond lengths. The La(1)-Co(1) bond length is 2.04 Å. W(1) is bonded in a 9-coordinate geometry to nine equivalent La(1) atoms. Co(1) is bonded in a distorted octahedral geometry to three equivalent La(1) atoms.
