Abstract

LiB(C2O4)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form corner-sharing LiO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 1.99–2.31 Å. B3+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of B–O bond distances ranging from 1.47–1.51 Å. There are three inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.32 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.22 Å) and one longer (1.34 Å) C–O bond length. In the third C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.32 Å) C–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one B3+ and one C3+ atom. In the second O2- site, O2- is bonded in a water-like geometry to one B3+ and one C3+ atom. In the third O2- site, O2- is bonded in a water-like geometry to one B3+ and one C3+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to one Li1+ and one C3+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one C3+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one C3+ atom.
