La Ta Co Co
LaTaCo2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 2-coordinate geometry to one Ta(1), two equivalent Co(1), and four equivalent Co(2) atoms. The La(1)-Ta(1) bond length is 3.18 Å. There is one shorter (1.81 Å) and one longer (2.18 Å) La(1)-Co(1) bond length. There are a spread of La(1)-Co(2) bond distances ranging from 2.49-3.19 Å. Ta(1) is bonded in a 13-coordinate geometry to one La(1), four equivalent Ta(1), four equivalent Co(1), and four equivalent Co(2) atoms. There are two shorter (3.13 Å) and two longer (3.15 Å) Ta(1)-Ta(1) bond lengths. There are a spread of Ta(1)-Co(1) bond distances ranging from 2.95-3.38 Å. There are a spread of Ta(1)-Co(2) bond distances ranging from 2.78-3.61 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted water-like geometry to two equivalent La(1), four equivalent Ta(1), and one Co(2) atom. The Co(1)-Co(2) bond length is 2.65 Å. In the second Co site, Co(2) is bonded in a 13-coordinate geometry to four equivalent La(1), four equivalent Ta(1), one Co(1), and four equivalent Co(2) atoms. There are two shorter (3.13 Å) and two longer (3.15 Å) Co(2)-Co(2) bond lengths.
