The crystal structure described by YCr(BO3)2 is Calcite-derived structured and crystallizes in the trigonal R-3 space group. Y(1) is bonded to six equivalent O(1) atoms to form YO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 57°. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 57°. B(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to one Y(1), one Cr(1), and one B(1) atom. is represented by the CIF file [CIF]
