Ta Fe Tc
TaTcFe crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 11-coordinate geometry to six equivalent Ta(1), two equivalent Tc(1), and three equivalent Fe(1) atoms. All Ta(1)-Ta(1) bond lengths are 2.76 Å. There is one shorter (3.37 Å) and one longer (3.57 Å) Ta(1)-Tc(1) bond length. There are a spread of Ta(1)-Fe(1) bond distances ranging from 3.30-3.53 Å. Tc(1) is bonded in a 2-coordinate geometry to two equivalent Ta(1) and two equivalent Fe(1) atoms. There is one shorter (1.16 Å) and one longer (1.65 Å) Tc(1)-Fe(1) bond length. Fe(1) is bonded in a 2-coordinate geometry to three equivalent Ta(1) and two equivalent Tc(1) atoms.
