N2 - Two new compounds, [ErAg(INA)2(C2O4)]·2H2O(1)(HINA=nicotinic acid) and [Tb0.8Y0.2Ag2(IN)4·(H2O)5]·NO3·2H2O(2)(HIN=isonicotinic acid), based on the {2} building units, have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, infrared spectroscopy, thermal analysis and powder X-ray diffraction(PXRD). Single-crystal X-ray diffraction data reveal that both compounds crystallized in the low-symmetry triclinic space group P1̄. Compound 1 is a 3D heterometallic coordination framework based on {Er2} clusters, oxalate ligands and bridging [Ag(INA)] linkers, while compound 2 consists of 0D [Tb0.8·Y0.2Ag2(IN)4(H2O)5]2 subunits that give a 3D supramolecular structure through hydrogen bond interaction. The photoluminescent properties of both compounds(1 and 2) were studied.
