ZnBr2 crystallizes in the monoclinic C2/c space group. The structure consists of a ZnBr2 framework. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one Br(1), one Br(2), one Br(3), and one Br(4) atom to form corner-sharing ZnBr4 tetrahedra. In the second Zn site, Zn(2) is bonded to one Br(2), one Br(6), one Br(8), and one Br(9) atom to form corner-sharing ZnBr4 tetrahedra. In the third Zn site, Zn(3) is bonded to one Br(1), one Br(4), one Br(5), and one Br(6) atom to form corner-sharing ZnBr4 tetrahedra. In the fourth Zn site, Zn(4) is bonded to one Br(3), one Br(5), one Br(7), and one Br(9) atom to form corner-sharing ZnBr4 tetrahedra. There are nine inequivalent Br sites. In the first Br site, Br(2) is bonded in a water-like geometry to one Zn(1) and one Zn(2) atom. In the second Br site, Br(4) is bonded in a water-like geometry to one Zn(1) and one Zn(3) atom. In the third Br site, Br(3) is bonded in a water-like geometry to one Zn(1) and one Zn(4) atom. In the fourth Br site, Br(1) is bonded in a water-like geometry to one Zn(1) and one Zn(3) atom. In the fifth Br site, Br(5) is bonded in a water-like geometry to one Zn(3) and one Zn(4) atom. In the sixth Br site, Br(6) is bonded in a water-like geometry to one Zn(2) and one Zn(3) atom. In the seventh Br site, Br(7) is bonded in a water-like geometry to two equivalent Zn(4) atoms. In the eighth Br site, Br(8) is bonded in a water-like geometry to two equivalent Zn(2) atoms. In the ninth Br site, Br(9) is bonded in a water-like geometry to one Zn(2) and one Zn(4) atom.
