The crystal structure described by SrCr2O10 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 10-coordinate geometry to one O(2), one O(3), one O(5), one O(6), one O(7), one O(8), two equivalent O(10), and two equivalent O(9) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing CrO4 tetrahedra. In the second Cr site, Cr(2) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form corner-sharing CrO4 tetrahedra. There are ten inequivalent O sites. In the first O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one Cr(2) atom. In the second O site, O(7) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one Cr(2) atom. In the third O site, O(8) is bonded in a bent 120 degrees geometry to one Sr(1) and one O(8) atom. In the fourth O site, O(1) is bonded in a single-bond geometry to one Cr(1) atom. In the fifth O site, O(9) is bonded in a single-bond geometry to two equivalent Sr(1) atoms. In the sixth O site, O(2) is bonded in a distorted single-bond geometry to one Sr(1) and one Cr(1) atom. In the seventh O site, O(10) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one O(10) atom. In the eighth O site, O(3) is bonded in a bent 150 degrees geometry to one Sr(1) and one Cr(1) atom. In the ninth O site, O(4) is bonded in a bent 150 degrees geometry to one Cr(1) and one Cr(2) atom. In the tenth O site, O(5) is bonded in a bent 150 degrees geometry to one Sr(1) and one Cr(2) atom. is represented by the CIF card [CIF]
