42 members new hydroquinone bridged supramolecular macrocycle and its tetra-nuclear mixed ligands Pt(II) complex: A synthetic, structural and spectroscopic investigation

A 2 + 2 supramolecular 42 members macrocycle (H4M) was synthesized in a simple one step reaction in good isolated yield from commercially available precursors. This macrocycle was used in the synthesis of trans-tetra‑platinum chloride mixed ligand complex (M-4Pt(pyridine)Cl) having characteristic UV-vis absorption in visible region λmax = 593 nm. The extremely simple synthetic procedure and the presence of multiple donor atoms, promises to make this macrocycle an appealing platform in organometallic and supramolecular chemistry.114
