TaNbCoIn crystallizes in the trigonal R3m space group. Ta(1) is bonded in a single-bond geometry to four equivalent Nb(1), one Co(1), and three equivalent In(1) atoms. There is one shorter (2.77 Å) and three longer (2.83 Å) Ta(1)-Nb(1) bond lengths. The Ta(1)-Co(1) bond length is 1.47 Å. All Ta(1)-In(1) bond lengths are 2.70 Å. Nb(1) is bonded in a 10-coordinate geometry to four equivalent Ta(1), three equivalent Co(1), and three equivalent In(1) atoms. All Nb(1)-Co(1) bond lengths are 2.70 Å. All Nb(1)-In(1) bond lengths are 2.70 Å. Co(1) is bonded in a single-bond geometry to one Ta(1), three equivalent Nb(1), and four equivalent In(1) atoms. There is one shorter (2.77 Å) and three longer (2.83 Å) Co(1)-In(1) bond lengths. In(1) is bonded in a 10-coordinate geometry to three equivalent Ta(1), three equivalent Nb(1), and four equivalent Co(1) atoms.
