One-Dimensional Corrugated Tape AgICoordination Polymers Constructed of Ag−C Bonds

Three one-dimensional (1D) polymers assembled of Ag−C bonds, [Ag 2 (μ 3 -L) 2 (MeCN)] n ( 1 − 3 ) [L = 4,4,4-trifluoro-1-phenyl-1,3-butandione (HTFPB) ( 1 ), 4,4,4-trifluoro-1-naphthyl-1,3-butandionate (HTFNB) ( 2 ), and 4,4,4-trifluoro-1-thiophen-1,3-butandione (HTFTB) ( 3 )] have been synthesized and characterized by elemental analysis, IR, and 1 H NMR spectroscopy. The thermal stability of compounds 1 − 3 were studied by thermal gravimetric and differential thermal analyses. The single-crystal X-ray structures of compounds 1 and 2 show two types of Ag I ions with coordination numbers of five and four. The Ag atoms contain strong Ag I −C methine bonds and thus produce 1D corrugated tape coordination polymers. Furthermore, the ligands and complexes 1 − 3 are luminescent in the solid state with emission maxima in the visible light region (λ max = 470 nm). The results of studies the stoichiometry and formation of complexes 1 − 3 in acetonitrile solution were found to be in support of their solid-state stoichiometries.
