CoH8(O2Br)2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two dibromocobalt;tetrahydrate molecules. Co(1) is bonded in a distorted octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent Br(1) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Co(1), one H(1), and one H(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Co(1), one H(3), and one H(4) atom. Br(1) is bonded in a distorted single-bond geometry to one Co(1) atom.
