The structure described by TaNiB2 crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded in a 13-coordinate geometry to four equivalent Ni(1), four equivalent B(2), and five equivalent B(1) atoms. Ni(1) is bonded in a 5-coordinate geometry to four equivalent Ta(1), 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 Ta(1), two equivalent Ni(1), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent Ta(1), three equivalent Ni(1), and two equivalent B(1) atoms. is represented by the CIF card [CIF]
