A 2-D CdI2coordination network with 7-oxabicyclo[2.2.1]-5-heptene-2,3-dicarboxylate: synthesis, crystal structure, and luminescent properties

The in situ reaction of Cd(ClO4)2·6H2O with 7-oxabicyclo[2.2.1]-5-heptene-2,3-dicarboxylic anhydride in the presence of lithium hydroxide affords a 2-D CdII coordination polymer, [Cd(L)(H2O)]∞ (1) (L = 7-oxabicyclo[2.2.1]-5-heptene-2,3-dicarboxylate), which exhibits an unusual (3,6)-connected (46.66.83)(43)2 CdI2-type topology. The luminescent and thermal properties of 1 were investigated.
