The structure described by Ge19P4(Br)4 crystallizes in the cubic P-43n space group. The structure consists of eight hydrogen bromide atoms inside a Ge19P4 framework. In the Ge19P4 framework, there are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one Ge(1), one Ge(2), one Ge(3), and one P(1) atom to form GeGe3P tetrahedra that share  a cornercorner with one Ge(3)Ge4 tetrahedra, corners with two equivalent Ge(2)Ge3P tetrahedra, corners with two equivalent P(1)Ge4 tetrahedra, and corners with seven equivalent Ge(1)Ge3P tetrahedra. In the second Ge site, Ge(2) is bonded to three equivalent Ge(1) and one P(1) atom to form GeGe3P tetrahedra that share corners with three equivalent Ge(3)Ge4 tetrahedra, corners with three equivalent P(1)Ge4 tetrahedra, and corners with six equivalent Ge(1)Ge3P tetrahedra. In the third Ge site, Ge(3) is bonded to four equivalent Ge(1) atoms to form GeGe4 tetrahedra that share corners with four equivalent Ge(1)Ge3P tetrahedra, corners with four equivalent Ge(2)Ge3P tetrahedra, and corners with four equivalent P(1)Ge4 tetrahedra. P(1) is bonded to one Ge(2) and three equivalent Ge(1) atoms to form PGe4 tetrahedra that share corners with three equivalent Ge(2)Ge3P tetrahedra, corners with three equivalent Ge(3)Ge4 tetrahedra, and corners with six equivalent Ge(1)Ge3P tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
