Re2Co(H2O3)4 is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Re2Co(H2O3)4 cluster. Re(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ReO4 tetrahedra that share  a cornercorner with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 38°. Co(1) is bonded to two equivalent O(1), two equivalent O(5), and two equivalent O(6) atoms to form CoO6 octahedra that share corners with two equivalent Re(1)O4 tetrahedra. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(6) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(6) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Re(1) and one Co(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Re(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Re(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one Re(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Co(1), one H(2), and one H(4) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Co(1), one H(1), and one H(3) atom.
