RbGeBr3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1/m space group. Rb(1) is bonded in a 10-coordinate geometry to one Ge(1), three equivalent Br(1), and six equivalent Br(2) atoms. Ge(1) is bonded in a 3-coordinate geometry to one Rb(1), one Br(1), and two equivalent Br(2) atoms. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one Ge(1) atom. In the second Br site, Br(2) is bonded to three equivalent Rb(1) and one Ge(1) atom to form a mixture of distorted corner and edge-sharing BrRb3Ge tetrahedra.
RbGeBr3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1/m space group. Rb(1) is bonded in a 10-coordinate geometry to one Ge(1), three equivalent Br(1), and six equivalent Br(2) atoms. The Rb(1)-Ge(1) bond length is 4.05 Å. There is one shorter (3.52 Å) and two longer (3.96 Å) Rb(1)-Br(1) bond lengths. There are a spread of Rb(1)-Br(2) bond distances ranging from 3.55-3.61 Å. Ge(1) is bonded in a 3-coordinate geometry to one Rb(1), one Br(1), and two equivalent Br(2) atoms. The Ge(1)-Br(1) bond length is 2.49 Å. Both Ge(1)-Br(2) bond lengths are 2.49 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one Ge(1) atom. In the second Br site, Br(2) is bonded to three equivalent Rb(1) and one Ge(1) atom to form a mixture of distorted corner and edge-sharing BrRb3Ge tetrahedra.
