A new cadmium(II) coordination polymer [Cd-2(L)(2)(bpy)](n)center dot nCH(3)OH (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 center dot 8/3H(2)O. 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.
