KGeBr3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. K(1) is bonded in a 12-coordinate geometry to four equivalent Br(2) and eight equivalent Br(1) atoms. Ge(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing GeBr6 octahedra. The corner-sharing octahedral tilt angles range from 6-9°. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Ge(1) atoms. In the second Br site, Br(2) is bonded in a distorted linear geometry to four equivalent K(1) and two equivalent Ge(1) atoms.
KGeBr3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. K(1) is bonded in a 12-coordinate geometry to four equivalent Br(2) and eight equivalent Br(1) atoms. There are a spread of K(1)-Br(2) bond distances ranging from 3.93-4.05 Å. There are a spread of K(1)-Br(1) bond distances ranging from 3.88-4.04 Å. Ge(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing GeBr6 octahedra. The corner-sharing octahedral tilt angles range from 6-9°. There is one shorter (2.62 Å) and one longer (2.99 Å) Ge(1)-Br(2) bond length. There are two shorter (2.60 Å) and two longer (3.01 Å) Ge(1)-Br(1) bond lengths. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Ge(1) atoms. In the second Br site, Br(2) is bonded in a distorted linear geometry to four equivalent K(1) and two equivalent Ge(1) atoms.
