TaNiAs crystallizes in the orthorhombic Pnma space group. Ta(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 Ta(1) and four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to five equivalent Ta(1) and four equivalent Ni(1) atoms.
TaNiAs crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded in a 10-coordinate geometry to five equivalent Ni(1) and five equivalent As(1) atoms. There are a spread of Ta(1)-Ni(1) bond distances ranging from 2.83-2.90 Å. There are a spread of Ta(1)-As(1) bond distances ranging from 2.67-2.72 Å. Ni(1) is bonded in a 4-coordinate geometry to five equivalent Ta(1) and four equivalent As(1) atoms. There are two shorter (2.36 Å) and two longer (2.37 Å) Ni(1)-As(1) bond lengths. As(1) is bonded in a 9-coordinate geometry to five equivalent Ta(1) and four equivalent Ni(1) atoms.
