The material structure described by K2MgCr2(H2O5)2 is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one K2MgCr2(H2O5)2 cluster. K(1) is bonded in a bent 120 degrees geometry to one H(1), one O(2), and one O(5) atom. Mg(1) is bonded in a linear geometry to two equivalent O(4) atoms. Cr(1) is bonded in a 2-coordinate geometry to one O(3) and one O(4) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a 3-coordinate geometry to one K(1), one H(2), and one O(1) atom. In the second H site, H(2) is bonded in a 3-coordinate geometry to one H(1), one O(1), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one H(1) and one H(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one K(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cr(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Mg(1), one Cr(1), and one H(2) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one K(1) atom. is represented by the CIF card [CIF]
