Ta Re Re Tc
TaRe2Tc crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaRe2Tc clusters. Ta(1) is bonded in a distorted single-bond geometry to one Re(1) and one Tc(1) atom. The Ta(1)-Re(1) bond length is 1.38 Å. The Ta(1)-Tc(1) bond length is 0.19 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a single-bond geometry to one Ta(1) atom. In the second Re site, Re(2) is bonded in a single-bond geometry to one Tc(1) atom. The Re(2)-Tc(1) bond length is 1.19 Å. Tc(1) is bonded in a single-bond geometry to one Ta(1) and one Re(2) atom.
