Sr4Be3Ge5 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to three equivalent Be(1), three equivalent Ge(1), three equivalent Ge(2), and three equivalent Ge(4) atoms to form SrBe3Ge9 cuboctahedra that share edges with six equivalent Sr(1)Be3Ge9 cuboctahedra, edges with six equivalent Sr(2)Be6Ge6 cuboctahedra,  a faceface with one Sr(2)Be6Ge6 cuboctahedra, and faces with seven equivalent Sr(1)Be3Ge9 cuboctahedra. In the second Sr site, Sr(2) is bonded to three equivalent Be(1), three equivalent Be(2), three equivalent Ge(2), and three equivalent Ge(3) atoms to form SrBe6Ge6 cuboctahedra that share edges with six equivalent Sr(1)Be3Ge9 cuboctahedra, edges with six equivalent Sr(2)Be6Ge6 cuboctahedra,  a faceface with one Sr(1)Be3Ge9 cuboctahedra, and faces with seven equivalent Sr(2)Be6Ge6 cuboctahedra. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted trigonal planar geometry to three equivalent Sr(1), three equivalent Sr(2), and three equivalent Ge(2) atoms. In the second Be site, Be(2) is bonded in a distorted trigonal planar geometry to six equivalent Sr(2) and three equivalent Ge(3) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Ge(4) atoms. In the second Ge site, Ge(2) is bonded in a distorted trigonal planar geometry to three equivalent Sr(1), three equivalent Sr(2), and three equivalent Be(1) atoms. In the third Ge site, Ge(3) is bonded in a distorted trigonal planar geometry to six equivalent Sr(2) and three equivalent Be(2) atoms. In the fourth Ge site, Ge(4) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Ge(1) atoms.
