TaCoAs crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded in a 5-coordinate geometry to five equivalent As(1) atoms. Co(1) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to five equivalent Ta(1) and four equivalent Co(1) atoms.
TaCoAs crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded in a 5-coordinate geometry to five equivalent As(1) atoms. There are a spread of Ta(1)-As(1) bond distances ranging from 2.65-2.68 Å. Co(1) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. There are three shorter (2.33 Å) and one longer (2.37 Å) Co(1)-As(1) bond length. As(1) is bonded in a 9-coordinate geometry to five equivalent Ta(1) and four equivalent Co(1) atoms.
