For coordination polymers it is reasonable to assume, and sometimes proven, that in solution, or indeed in a precrystalline state, if we do solidstate synthesis, there are polynuclear entities that without doubt can be called (polymer) macromolecules. These then crystalize or polymerize into the coordination polymer. S. R. BATTEN et al.
