The material structure described by Co2CuGe2 crystallizes in the orthorhombic Pmma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 11-coordinate geometry to two equivalent Co(2), four equivalent Cu(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Co site, Co(2) is bonded in a 10-coordinate geometry to two equivalent Co(1), two equivalent Co(2), two equivalent Ge(2), and four equivalent Ge(1) atoms. Cu(1) is bonded to four equivalent Co(1), two equivalent Cu(1), two equivalent Ge(1), and four equivalent Ge(2) atoms to form a mixture of corner, edge, and face-sharing CuCo4Cu2Ge6 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to two equivalent Co(1), four equivalent Co(2), and two equivalent Cu(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Co(2), three equivalent Co(1), and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
