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.
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. All Sr(1)-Pb(1) bond lengths are 3.69 Å. There are four shorter (3.27 Å) and two longer (3.47 Å) Sr(1)-Ge(1) bond lengths. Pb(1) is bonded in a distorted q6 geometry to eight equivalent Sr(1) and two equivalent Ge(1) atoms. Both Pb(1)-Ge(1) bond lengths are 3.11 Å. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1), one Pb(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.51 Å.
