title: Monomeric mixed cadmium-2,2'-dipyridylamine complex derived from ferrocenecarboxylic acid: Structural, electrochemical and biological studies.
abstract: A mixed Cd(II) complex {[Cd(FcCOO)2(dpyam)(H2O)][Cd(dpyam)2 (H2O)2]·(ClO4)2·CH3OH} (1) (where FcCOO=ferrocenecarboxylic acid and dpyam=2,2'-dipyridylamine), has been synthesized and characterized by FT-IR, (1)H &(13)C NMR, UV-Vis spectroscopy and elemental analysis. The molecular structure of compound 1 has been determined by the single crystal X-ray diffraction technique, which consists of mixed two different cadmium(II) complexes and two uncoordinated perchlorate ions. The crystal packing shows that the compound 1 self-assembled by intermolecular hydrogen bonding via pyridyl N-H⋯O and coordinated water O⋯H-O-H⋯O, to afford the molecule 2D supramolecular network. Compound 1 exhibits high-energy intraligand (π-π(∗)) fluorescence emission. In electrochemical studies of compound 1 shows negative potential compared with ferrocenecarboxylic acid due to formation of coordination complex with Cd ions. The antibacterial study against the distinct bacterial strains show compound 1 has significant activity.
