CaV(GeO3)4 crystallizes in the orthorhombic Amm2 space group. Ca(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(4) atoms. V(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. Ge(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing GeO6 octahedra. The corner-sharing octahedral tilt angles range from 27-53°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Ca(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ca(1), one V(1), and two equivalent Ge(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one V(1) and two equivalent Ge(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Ca(1) and two equivalent Ge(1) atoms. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one V(1) and two equivalent Ge(1) atoms.
