Abstract
AbstractA new 3D organo‐silver(I) crystalline complex of [(MPC)4(CF3COO)8Ag10]n (MPC = 4‐methyl‐7‐propargyloxy coumarin) (JMSU‐Ag10) has been successfully synthesized. The crystal structure analysis shows that the 10‐core silver(I) cluster (Ag10) can be considered as the subunit of JMSU‐Ag10 with different AgAg argentophilic interactions. By the protection of organic ligands and AgAg interactions, the Ag10 subunits further compose a chain structure, and then the trifluoroacetate or the MPC ligands bridge the 1D silver(I) chains along different directions to form the 3D framework. Furthermore, JMSU‐Ag10 can be used to detect the hydrazine due to that the Ag+ ions can be reduced to Ag0 species with strong UV–vis absorption. Interestingly, the reduced JMSU‐Ag10 by hydrazine can be further used to catalyze the reduction of 4‐nitrophenol to form 4‐aminophenol. This work provides a new strategy for the design, synthesis, and the cyclic utilization of functional organo‐silver(I) crystalline materials.
