The material structure described by Sr2PbGe2 crystallizes in the orthorhombic Cmmm space group. Sr(1) is bonded in a 10-coordinate geometry to four equivalent Pb(1) and six equivalent Ge(1) atoms. Pb(1) is bonded in a distorted q6 geometry to eight equivalent Sr(1) and two equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1), one Pb(1), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
