Ta Nb Nb Mo
TaNb2Mo crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Nb(2) and two equivalent Mo(1) atoms. There is one shorter (3.37 Å) and one longer (3.67 Å) Ta(1)-Nb(2) bond length. There is one shorter (2.01 Å) and one longer (2.48 Å) Ta(1)-Mo(1) bond length. There are two inequivalent Nb sites. In the first Nb site, Nb(1) is bonded in a 2-coordinate geometry to two equivalent Nb(2) and two equivalent Mo(1) atoms. There is one shorter (2.66 Å) and one longer (3.03 Å) Nb(1)-Nb(2) bond length. There is one shorter (2.06 Å) and one longer (2.52 Å) Nb(1)-Mo(1) bond length. In the second Nb site, Nb(2) is bonded in a 10-coordinate geometry to two equivalent Ta(1), two equivalent Nb(1), and six equivalent Nb(2) atoms. There are four shorter (2.87 Å) and two longer (3.26 Å) Nb(2)-Nb(2) bond lengths. Mo(1) is bonded in a 4-coordinate geometry to two equivalent Ta(1) and two equivalent Nb(1) atoms.
