Halogen-substituted salicylhydroximate copper(ii) metallacrowns: from synthesis and structures to novel applications

New halogen-substituted salicylhydroximate copper(II) metallacrowns were synthesized from Cu(OAc)2 and the corresponding salicylhydroxamic acids. Their molecular structure was determined by single crystal X-ray diffraction. The compounds obtained represent the first members of the metallacrown family that can be used as components of active initiators for the photopolymerization of oligo-carbonate dimethacrylate by visible light.
