A 3D cadmium(II) coordination polymer constructed from new β-diketone-functionalized pyridinecarboxylate and 4,4′-bipyridine ligands

• A Cd coordination polymer is constructed from new β-diketonate and 4,4′-bpy ligands.
• This polymer shows an exceptional non-interpenetrating three-dimensional framework.
• The polymer exhibits an intense emission at room temperature.

A new cadmium(II) coordination polymer [Cd2(L)2(bpy)]n·nCH3OH (1) (H2L = 2-(3-oxo-3-phenylpropionyl)-6-pyridinecarboxylic acid N-oxide, bpy = 4,4′-bipyridine), has been synthesized from the reaction of H2L, 4,4′-bipyridine with CdSO4·8/3H2O. Compound 1 is an exceptional non-interpenetrating three-dimensional framework and contains double helical chains and rare cross bpy configuration. Interestingly, these helical chains can span two different directions on other alternate layers. Compound 1 shows intense photoluminescence at room temperature.
