The material described by K3Cr(HO)6 crystallizes in the trigonal R-3c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent H(1) and six equivalent O(1) atoms. Cr(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. H(1) is bonded in a single-bond geometry to one K(1) and one O(1) atom. O(1) is bonded in a distorted single-bond geometry to three equivalent K(1), one Cr(1), and one H(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
