KZnBr3(H2)3 crystallizes in the monoclinic P2_1/c space group. The structure consists of eight 1333-74-0 atoms and four molecular hydrogen molecules inside a KZnBr3 framework. In the KZnBr3 framework, K(1) is bonded to one Br(3), two equivalent Br(2), and three equivalent Br(1) atoms to form a mixture of distorted corner and edge-sharing KBr6 pentagonal pyramids. Zn(1) is bonded in a trigonal planar geometry to one Br(1), one Br(2), and one Br(3) atom. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Zn(1) atom. In the second Br site, Br(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Zn(1) atom. In the third Br site, Br(3) is bonded in a distorted single-bond geometry to one K(1) and one Zn(1) atom.
