Materials Data on KGeBr3 by Materials Project
KGeBr3 is Potassium chlorate structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. K1+ is bonded to seven Br1- atoms to form distorted edge-sharing KBr7 hexagonal pyramids. There are a spread of K–Br bond distances ranging from 3.40–3.56 Å. Ge2+ is bonded in a 3-coordinate geometry to three Br1- atoms. There are one shorter (2.53 Å) and two longer (2.54 Å) Ge–Br bond lengths. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded to three equivalent K1+ and one Ge2+ atom to form a mixture of distorted edge and corner-sharing BrK3Ge tetrahedra. In the second Br1- site, Br1- is bonded in a distorted L-shaped geometry to one K1+ and one Ge2+ atom.
