Ta Ta W Au
Ta2WAu crystallizes in the monoclinic Pm space group. Ta(1) is bonded in a 5-coordinate geometry to one Ta(1), two equivalent W(1), and two equivalent Au(1) atoms. The Ta(1)-Ta(1) bond length is 1.47 Å. There is one shorter (2.67 Å) and one longer (3.19 Å) Ta(1)-W(1) bond length. There is one shorter (2.67 Å) and one longer (3.19 Å) Ta(1)-Au(1) bond length. W(1) is bonded in a 1-coordinate geometry to four equivalent Ta(1) and one Au(1) atom. The W(1)-Au(1) bond length is 1.01 Å. Au(1) is bonded in a 1-coordinate geometry to four equivalent Ta(1) and one W(1) atom.
