The structure described by NbNiAs crystallizes in the orthorhombic Pnma space group. Nb(1) is bonded in a 10-coordinate geometry to five equivalent Ni(1) and five equivalent As(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to five equivalent Nb(1) and four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to five equivalent Nb(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
