Synthesis, structure and properties of one 2-D Ag(I) complex based on trinuclear silver(I) cluster and arene-linked bis(pyrazolyl)methane ligand

One 2D coordination polymer, [Ag2(Lp)1.5(NO3)](NO3) (1) (Lp = p − [CH(pz)2]2C6H4,), has been successfully synthesized under solvothermal conditions by the reaction of arene-linked p-bis[bis(1-pyrazolyl)methyl]benzene ligand with AgNO3. Compound 1 presents the first two-dimensional (2D) framework of trinuclear Ag cluster and Lp ligand, and exhibits a three-dimensional (3D) supramolecular structure supported by the weak interactions between neighboring sheets. It was characterized by IR, PXRD, single-crystal X-ray diffraction and thermogravimetric analysis. The fluorescence property of compound 1 has also been studied.
