The structure described by NaCr2In(H2O5)2 crystallizes in the monoclinic C2/m space group. Na(1) is bonded to two equivalent O(2) and four equivalent O(4) atoms to form NaO6 octahedra that share corners with six equivalent Cr(1)O4 tetrahedra and edges with two equivalent In(1)O6 octahedra. Cr(1) is bonded to one O(2), one O(3), and two equivalent O(4) atoms to form CrO4 tetrahedra that share corners with two equivalent In(1)O6 octahedra and corners with three equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-69°. In(1) is bonded to two equivalent O(1) and four equivalent O(4) atoms to form InO6 octahedra that share corners with four equivalent Cr(1)O4 tetrahedra and edges with two equivalent Na(1)O6 octahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) and one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one In(1), one H(1), and one H(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Na(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to one Cr(1) and one H(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(1), one Cr(1), and one In(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
