The material described by Y2Ba3Cu2PtO10 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 9-coordinate geometry to two equivalent O(2), three equivalent O(1), and four equivalent O(3) atoms. In the second Ba site, Ba(2) is bonded in a body-centered cubic geometry to four equivalent O(2) and four equivalent O(3) atoms. Y(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(3), and four equivalent O(2) atoms. Pt(1) is bonded in an octahedral geometry to two equivalent O(1) and four equivalent O(3) atoms. Cu(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ba(1), one Y(1), one Pt(1), and one Cu(1) atom to form a mixture of distorted edge, face, and corner-sharing OBa3YCuPt octahedra. The corner-sharing octahedral tilt angles range from 0-69°. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), two equivalent Y(1), and one Cu(1) atom. In the third O site, O(3) is bonded to one Ba(2), two equivalent Ba(1), one Y(1), one Pt(1), and one Cu(1) atom to form a mixture of distorted edge, face, and corner-sharing OBa3YCuPt octahedra. The corner-sharing octahedral tilt angles range from 0-74°. is represented by the CIF file [CIF]
