CsReBr4 crystallizes in the orthorhombic Pbca space group. Cs(1) is bonded in a 11-coordinate geometry to two equivalent Br(3), three equivalent Br(1), three equivalent Br(2), and three equivalent Br(4) atoms. Re(1) is bonded in a 5-coordinate geometry to one Re(1), one Br(1), one Br(2), one Br(3), and one Br(4) atom. There are four inequivalent Br sites. In the first Br site, Br(3) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Re(1) atom. In the second Br site, Br(4) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Re(1) atom. In the third Br site, Br(1) is bonded to three equivalent Cs(1) and one Re(1) atom to form distorted corner-sharing BrCs3Re trigonal pyramids. In the fourth Br site, Br(2) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Re(1) atom.
