Materials Data on NaHCO2 by Materials Project
HCOONa is Ullmanite-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Na1+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing NaO6 pentagonal pyramids. There are a spread of Na–O bond distances ranging from 2.43–2.54 Å. C2+ is bonded in a trigonal planar geometry to one H1+ and two equivalent O2- atoms. The C–H bond length is 1.11 Å. Both C–O bond lengths are 1.27 Å. H1+ is bonded in a single-bond geometry to one C2+ atom. O2- is bonded in a 1-coordinate geometry to three equivalent Na1+ and one C2+ atom.
