The structure described by Na2SnCPO7 crystallizes in the monoclinic P2_1/m space group. Na(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Sn(1) is bonded to one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms to form distorted SnO6 octahedra that share corners with four equivalent P(1)O4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. P(1) is bonded to one O(5), one O(6), and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with four equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-66°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to two equivalent Na(1), one Sn(1), and one C(1) atom. In the third O site, O(3) is bonded to two equivalent Na(1), one Sn(1), and one C(1) atom to form distorted corner-sharing ONa2SnC trigonal pyramids. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(1), one Sn(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1), one Sn(1), and one P(1) atom. In the sixth O site, O(6) is bonded to two equivalent Na(1), one Sn(1), and one P(1) atom to form distorted corner-sharing ONa2SnP tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
