The material described by Co(GeO3)2 crystallizes in the monoclinic P2_1/c space group. Co(1) is bonded to one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted CoO6 pentagonal pyramids that share corners with three equivalent Ge(1)O4 tetrahedra, corners with two equivalent Ge(2)O5 trigonal bipyramids, edges with two equivalent Co(1)O6 pentagonal pyramids, and  an edgeedge with one Ge(2)O5 trigonal bipyramid. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(4), one O(5), and two equivalent O(2) atoms to form GeO4 tetrahedra that share corners with three equivalent Co(1)O6 pentagonal pyramids and corners with two equivalent Ge(1)O4 tetrahedra. In the second Ge site, Ge(2) is bonded to one O(6), two equivalent O(1), and two equivalent O(3) atoms to form distorted GeO5 trigonal bipyramids that share corners with two equivalent Co(1)O6 pentagonal pyramids, corners with two equivalent Ge(2)O5 trigonal bipyramids,  an edgeedge with one Co(1)O6 pentagonal pyramid, and  an edgeedge with one Ge(2)O5 trigonal bipyramid. There are six inequivalent O sites. In the first O site, O(6) is bonded in a trigonal non-coplanar geometry to two equivalent Co(1) and one Ge(2) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ge(2) atoms. In the third O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. In the fourth O site, O(3) is bonded in a distorted T-shaped geometry to one Co(1) and two equivalent Ge(2) atoms. In the fifth O site, O(4) is bonded in a bent 150 degrees geometry to one Co(1) and one Ge(1) atom. In the sixth O site, O(5) is bonded in a trigonal planar geometry to two equivalent Co(1) and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
