Syntheses, Crystal Structures and Fluorescence Properties of Two Compounds Constructed by Aromatic Carboxylates and 4,4′-Bis(imidazol-I-yl)-phenyl Sulphone

Two coordination polymers, namely {[Cd(L)(oba)]center dot 3.5H(2)O}(n) (1) and {[Cd(L)(2)](p-bdc)}(n), (2) have been obtained by the reaction of cadmium nitrate, 4,4'-bis(imidazol-l-yl)-phenyl sulphone (L) with two aromatic carboxylic acids, 4,4'-oxydibenzoic acid (H(2)oba), terephthalic acid (p-H(2)bdc). They were characterized by IR, elemental analysis and X-ray diffraction. Compound 1 exhibits 4-connected 2-fold interpenetrating 3D networks with the point symbol of {6(5).8}. Compound 2 can be characterized as a 4-connected sql tetragonal planar network with the point symbol of {4(4).6(2)}. The luminescent properties of two compounds have also been investigated.
