This work reports synthesis of tris ‐chelated Co 3+ complexes, either having mer or fac geometries, and bis ‐chelated Co 3+ complexes containing appended aryldicarboxylic acid groups. The tris ‐chelated complexes offer six appended –COOH groups while bis ‐chelated complexes provide eight –COOH groups. Both tris ‐ and bis ‐chelated complexes participate in intermolecular hydrogen bonding to generate complicated yet interesting self‐assembled architectures that has been simplified by the topological analyses. We evaluate the effect of tris ‐ versus bis ‐chelated complexes; mer versus fac geometrical forms; lattice solvent molecules; and cations on the hydrogen bonding based self‐assemblies.
