TaNbMo2 crystallizes in the trigonal R3m space group. Ta(1) is bonded in a 1-coordinate geometry to one Nb(1), three equivalent Mo(1), and four equivalent Mo(2) atoms. The Ta(1)-Nb(1) bond length is 1.70 Å. All Ta(1)-Mo(1) bond lengths are 2.70 Å. There is one shorter (2.60 Å) and three longer (2.87 Å) Ta(1)-Mo(2) bond lengths. Nb(1) is bonded in a 1-coordinate geometry to one Ta(1), three equivalent Mo(2), and four equivalent Mo(1) atoms. All Nb(1)-Mo(2) bond lengths are 2.70 Å. There is one shorter (2.60 Å) and three longer (2.87 Å) Nb(1)-Mo(1) bond lengths. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 10-coordinate geometry to three equivalent Ta(1), four equivalent Nb(1), and three equivalent Mo(2) atoms. All Mo(1)-Mo(2) bond lengths are 2.70 Å. In the second Mo site, Mo(2) is bonded in a 10-coordinate geometry to four equivalent Ta(1), three equivalent Nb(1), and three equivalent Mo(1) atoms.
