CdGe(BiO3)2 crystallizes in the orthorhombic Pbcn space group. Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(3) atoms. Ge(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Bi(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ge(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Cd(1), one Ge(1), and one Bi(1) atom. In the third O site, O(3) is bonded to two equivalent Cd(1) and two equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing OCd2Bi2 tetrahedra.
CdGe(BiO3)2 crystallizes in the orthorhombic Pbcn space group. Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(3) atoms.
