文摘

Four rare organosilver(I) coordination polymers, namely [Ag₂L1]_n (1), [Ag₂L1(H₂O)]_n (2), [Ag₂L2(H₂O)]_n (3), and [Ag₅(L3)(NH₃)₂(NO₃)]_n (4) (H₂L1 = 2-hydroxy-5-chlorobenzenesulfonic acid, H₂L2 = 2-hydroxy-5-bromobenzenesulfonic acid, H₄L3 = 4,6-dihydroxy-1,3-benzenedisulfonic acid), have been successfully prepared and characterized by elemental analysis, IR, PL, TG, and single-crystal X-ray diffraction. Complex 1 possesses a two-dimensional (2-D) inorganic layer structure. The 畏¹ silver(I)鈭抌enzene interactions brings the chlorophenyl moieties closer to the Ag鈭扴鈭扥 layers and thus remarkably decreases the gallery height between the two adjacent layers. Complexes 2 and 3 contain pseudocubic tetranuclear units which are further bridged by the 畏² silver(I)鈭抌enzene interactions to form a new type of 2-D hybrid layer structure which is completely different from that of 1. Complex 4 has a three-dimensional (3-D) organosilver(I) coordination framework, in which the fully deprotonated L3^4鈭?/b> tetraanion presents an unprecedented coordination mode and bridges 14 silver(I) ions; the unusual 渭₂-畏³-benzene mode of the phenyl ring has not been reported to date.
