Synthesis, Crystal Structure and Fluorescent Properties of Silver and Cadmium Complexes(1)

Two new complexes [Ag(bix)](n)center dot nNAA center dot nH(2)O (1) and [Cd(NAA)(phen)(2)(H2O)](2)center dot 2CH(3)COO-center dot H2O (2) (bix = 1,4-bis(imidazol-1-ylmethyl)benzene, HNAA = alpha-naphthylacetic acid, phen = 1,10-phenanthroline) have been successfully synthesized under hydrothermal conditions. Their structures have been determined by elemental analyses, IR spectroscopy, TG and single-crystal X-ray diffraction analysis. The intermolecular hydrogen bonding or pi-pi stacking interactions extend the complexes into a 3D supramolecular structure. Moreover, the luminescent properties of complex 2 have been investigated in the solid state.
