The structure described by NbCoB2 crystallizes in the orthorhombic Pnma space group. Nb(1) is bonded in a 9-coordinate geometry to four equivalent B(2) and five equivalent B(1) atoms. Co(1) is bonded in a 5-coordinate geometry to two equivalent B(1) and three equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to five equivalent Nb(1), two equivalent Co(1), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Nb(1), three equivalent Co(1), and two equivalent B(1) atoms. is represented by the CIF card [CIF]
