Abstract
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 η1 silver(I)−benzene interactions brings the chlorophenyl moieties closer to the Ag−S−O 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 η2 silver(I)−benzene 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 L34− tetraanion presents an unpr...
