Co Co B W
WCo2B crystallizes in the trigonal R3m space group. W(1) is bonded in a 2-coordinate geometry to one Co(2), three equivalent Co(1), and one B(1) atom. The W(1)-Co(2) bond length is 2.06 Å. All W(1)-Co(1) bond lengths are 2.35 Å. The W(1)-B(1) bond length is 1.73 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 10-coordinate geometry to three equivalent W(1), three equivalent Co(2), and four equivalent B(1) atoms. All Co(1)-Co(2) bond lengths are 2.35 Å. There is one shorter (2.06 Å) and three longer (2.55 Å) Co(1)-B(1) bond lengths. In the second Co site, Co(2) is bonded in a distorted single-bond geometry to one W(1) and three equivalent Co(1) atoms. B(1) is bonded in a 1-coordinate geometry to one W(1) and four equivalent Co(1) atoms.
