The material described by Li2CuGe crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to four equivalent Cu(1) and four equivalent Ge(1) atoms. In the second Li site, Li(2) is bonded in a 4-coordinate geometry to four equivalent Cu(1) and four equivalent Ge(1) atoms. Cu(1) is bonded in a 12-coordinate geometry to four equivalent Li(1), four equivalent Li(2), and four equivalent Ge(1) atoms. Ge(1) is bonded in a 12-coordinate geometry to four equivalent Li(1), four equivalent Li(2), and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
