are 4.82 net in a fluorescent Cd-organic framework

The reaction of CdCl2 with picolinic acid in the presence of isonicotinic acid in DMF yielded a Cd(II) complex, [Cd(pyc)(μ-Cl)]n (1; pyc = 2-pyridinecarboxylate), containing a rare two-dimensional 4.82 net constructed by Cd ions, μ-O and μ-Cl bridges. It exhibits photoluminescence at 440 nm (λex = 322 nm).
