Li2Ti(CoO3)2 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. Ti(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form TiO6 octahedra that share edges with six equivalent Co(1)O6 octahedra. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share edges with three equivalent Ti(1)O6 octahedra and edges with three equivalent Co(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Ti(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded to two equivalent Li(1), one Ti(1), and two equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing OLi2TiCo2 square pyramids.
Li2Ti(CoO3)2 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. All Li(1)-O(2) bond lengths are 2.05 Å. Ti(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form TiO6 octahedra that share edges with six equivalent Co(1)O6 octahedra. Both Ti(1)-O(1) bond lengths are 1.93 Å. All Ti(1)-O(2) bond lengths are 2.02 Å. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share edges with three equivalent Ti(1)O6 octahedra and edges with three equivalent Co(1)O6 octahedra. Both Co(1)-O(1) bond lengths are 1.98 Å. There are two shorter (2.01 Å) and two longer (2.06 Å) Co(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Ti(1) and two equivalent Co(1) atoms. In the second O site, O(2) is bonded to two equivalent Li(1), one Ti(1), and two equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing OLi2TiCo2 square pyramids.
