Figure 3
The hydrogen bonding between adjacent coordination chains, which is shown by the dotted red lines. Two successive layers are marked in blue and gray and the Li+ ions are presented as coodination tetrahedra, while considering only the four shortest coordination bonds for clarity. The purple lines identify the directions of the coordination chains, which coincide with the crystal directions (110) and (10).
