The compound described by Ca3GeO4Cl2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), two equivalent O(1), and three equivalent Cl(1) atoms. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to one O(2), one O(3), two equivalent O(1), and two equivalent Cl(1) atoms. Ge(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Ca(2), two equivalent Ca(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a trigonal pyramidal geometry to one Ca(2), two equivalent Ca(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ca(2), two equivalent Ca(1), and one Ge(1) atom. Cl(1) is bonded in a distorted rectangular see-saw-like geometry to one Ca(2) and three equivalent Ca(1) atoms. is represented by the CIF card [CIF]
