Na2TmCPO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.25–2.70 Å. Tm3+ is bonded to six O2- atoms to form TmO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Tm–O bond distances ranging from 2.21–2.27 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.25–1.34 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent TmO6 octahedra. The corner-sharing octahedra tilt angles range from 40–59°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Na1+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Tm3+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two equivalent Na1+, one Tm3+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one Tm3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Tm3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Tm3+, and one P5+ atom.
