The compound described by HfNiAs crystallizes in the orthorhombic Pnma space group. Hf(1) is bonded in a 11-coordinate geometry to six equivalent Ni(1) and five equivalent As(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Hf(1) and four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to five equivalent Hf(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
