LiBi3O4Cl2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Li1+ is bonded in a distorted square co-planar geometry to four equivalent O2- atoms. All Li–O bond lengths are 2.06 Å. There are three inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four Cl1- atoms. All Bi–O bond lengths are 2.25 Å. There are two shorter (3.39 Å) and two longer (3.46 Å) Bi–Cl bond lengths. In the second Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four Cl1- atoms. All Bi–O bond lengths are 2.26 Å. There are two shorter (3.28 Å) and two longer (3.35 Å) Bi–Cl bond lengths. In the third Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- and four Cl1- atoms. All Bi–O bond lengths are 2.28 Å. There are two shorter (3.26 Å) and two longer (3.32 Å) Bi–Cl bond lengths. O2- is bonded to one Li1+ and three Bi3+ atoms to form a mixture of distorted corner and edge-sharing OLiBi3 tetrahedra. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 6-coordinate geometry to six Bi3+ atoms. In the second Cl1- site, Cl1- is bonded in a 6-coordinate geometry to six Bi3+ atoms.
