Abstract

HCO2Li crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.00 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–1.97 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. There is one shorter (1.97 Å) and three longer (1.99 Å) Li–O bond length. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of corner and edge-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–2.00 Å. There are four inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. In the second C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. Both C–O bond lengths are 1.27 Å. In the third C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. In the fourth C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.11 Å. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one C2+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C2+ atom. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one C2+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C2+ atom. In the fifth O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one C2+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C2+ atom. In the seventh O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one C2+ atom. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C2+ atom.
