KCaBr3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. The structure consists of two 7440-09-7 atoms inside a CaBr3 framework. In the CaBr3 framework, Ca(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing CaBr6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a linear geometry to two equivalent Ca(1) atoms. In the second Br site, Br(2) is bonded in a linear geometry to two equivalent Ca(1) atoms.

In the CaBr3 framework, Ca(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing CaBr6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. Both Ca(1)-Br(2) bond lengths are 2.86 Å. There are two shorter (2.84 Å) and two longer (2.88 Å) Ca(1)-Br(1) bond lengths. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a linear geometry to two equivalent Ca(1) atoms. In the second Br site, Br(2) is bonded in a linear geometry to two equivalent Ca(1) atoms.
