ReTcGe crystallizes in the trigonal R3m space group. Re(1) is bonded in a distorted single-bond geometry to one Tc(1) and three equivalent Ge(1) atoms. The Re(1)-Tc(1) bond length is 0.78 Å. All Re(1)-Ge(1) bond lengths are 2.44 Å. Tc(1) is bonded in a single-bond geometry to one Re(1) and six equivalent Ge(1) atoms. There are three shorter (2.72 Å) and three longer (3.16 Å) Tc(1)-Ge(1) bond lengths. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Re(1) and six equivalent Tc(1) atoms.
