The structure described by SrPbGeO4 crystallizes in the orthorhombic P2_12_12_1 space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Pb(1) is bonded in a distorted T-shaped geometry to one O(1), one O(3), and one O(4) atom. Ge(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(1), one Pb(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Sr(1) and one Ge(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one Pb(1), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(1), one Pb(1), and one Ge(1) atom. is represented by the CIF card [CIF]
