Co Tc Ge
TcCoGe crystallizes in the trigonal R3m space group. Tc(1) is bonded to one Co(1) and three equivalent Ge(1) atoms to form distorted TcCoGe3 tetrahedra that share corners with three equivalent Co(1)TcGe3 tetrahedra, corners with six equivalent Tc(1)CoGe3 tetrahedra, and edges with three equivalent Co(1)TcGe3 tetrahedra. The Tc(1)-Co(1) bond length is 1.63 Å. All Tc(1)-Ge(1) bond lengths are 2.46 Å. Co(1) is bonded to one Tc(1) and three equivalent Ge(1) atoms to form distorted CoTcGe3 tetrahedra that share corners with three equivalent Tc(1)CoGe3 tetrahedra, corners with six equivalent Co(1)TcGe3 tetrahedra, and edges with three equivalent Tc(1)CoGe3 tetrahedra. All Co(1)-Ge(1) bond lengths are 2.46 Å. Ge(1) is bonded in a 6-coordinate geometry to three equivalent Tc(1) and three equivalent Co(1) atoms.
