Two genuine supramolecular isomers (Lp = p-[CH(pz)2]2C6H4), have been successfully obtained under similar solvothermal conditions by the reaction of arene-linked p-bis[bis(1-pyrazolyl)methyl]benzene ligand with AgNO3. Both of the compounds are made of unusual meso-helical chains and present a three-dimensional (3D) supramolecular structure. Compounds 1 and 2 were characterized by elemental analyses, IR spectra, single-crystal X-ray diffraction and thermogravimetric (TG) analyses. The fluorescence property of them has also been studied.
