TaZn crystallizes in the triclinic P-1 space group. Ta(1) is bonded to five equivalent Zn(1) atoms to form a mixture of distorted corner and edge-sharing TaZn5 trigonal bipyramids. There are a spread of Ta(1)-Zn(1) bond distances ranging from 1.87-3.07 Å. Zn(1) is bonded to five equivalent Ta(1) atoms to form a mixture of distorted corner and edge-sharing ZnTa5 trigonal bipyramids.
