    • The incorporation of a hybrid organic-organometallic bis-β-lactam framework possesses an additional interest. Many biologically active natural products are macrocycles. Therefore, the compounds synthesized herein combine three different attractive features, the βlactam ring, the square-planar metal center, and the macrocyclic structure making them a sort of bio-organometallic chimeras

    • The synthesis of macrocycles by metal-coordination bonds through the directional-bonding approach has two major requirements at its most basic level. The first calls for precursors with predefined angles and symmetry for the desired product form. The second dictates that the precursors should be mixed in the ratios appropriate for the chosen outcome. What is more usual is that when reacting precursors with predefined angles and symmetry, mixtures of macrocycles of different sizes will be formed in different ratios. Then, a careful tuning of the reaction conditions (order of precursor addition, choice of solvent system, concentration, temperature, and often even the rate of mixing of the two building blocks) is required to optimize the yields in the desired self-assembly process
