A distorted square-planar coordinated Li+ ion is located in the pocket of the triple-stranded helicate (structure shown on the right) formed by self-assembly of three ethylene-bridged bis(catecholate) ligands, and two titanium(IV) ions. This unusual coordination geometry is the result of steric effects and stabilizing hydrogen bonds between the two water molecules bound to the Li+ ion and oxygen atoms of the ligands.
