Na3Yb(CO3)2F2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are six inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to five O2- and two F1- atoms. There are a spread of Na–O bond distances ranging from 2.47–2.98 Å. There are one shorter (2.34 Å) and one longer (2.38 Å) Na–F bond lengths. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to four O2- and two F1- atoms. There are a spread of Na–O bond distances ranging from 2.38–2.64 Å. There are one shorter (2.31 Å) and one longer (2.38 Å) Na–F bond lengths. In the third Na1+ site, Na1+ is bonded in a 7-coordinate geometry to five O2- and two F1- atoms. There are a spread of Na–O bond distances ranging from 2.43–2.96 Å.
