The crystal structure described by SrY2O4 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to one O(4), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing YO6 octahedra. The corner-sharing octahedral tilt angles range from 50-64°. In the second Y site, Y(2) is bonded to one O(2), two equivalent O(4), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing YO6 octahedra. The corner-sharing octahedral tilt angles range from 50-64°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1) and three equivalent Y(2) atoms to form a mixture of distorted corner and edge-sharing OSr2Y3 trigonal bipyramids. In the second O site, O(2) is bonded to two equivalent Sr(1), one Y(2), and two equivalent Y(1) atoms to form a mixture of distorted corner and edge-sharing OSr2Y3 trigonal bipyramids. In the third O site, O(3) is bonded to two equivalent Sr(1) and three equivalent Y(1) atoms to form a mixture of corner and edge-sharing OSr2Y3 square pyramids. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to two equivalent Sr(1), one Y(1), and two equivalent Y(2) atoms. is represented by the CIF card [CIF]
