La(OH)CrO4 crystallizes in the monoclinic P2_1/c space group. La(1) is bonded in a 9-coordinate geometry to one O(3), one O(4), two equivalent O(2), two equivalent O(5), and three equivalent O(1) atoms. Cr(1) is bonded in a tetrahedral geometry to one O(2), one O(3), one O(4), and one O(5) atom. H(1) is bonded in a single-bond geometry to one O(1) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent La(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to one La(1) and one Cr(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one La(1) and one Cr(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to two equivalent La(1) and one Cr(1) atom.
