| Abstract: | Urothermal reaction of Zn(NO3)2 · 6H2O, Htrz and NH2H2pdc or H2pdc affords two new compounds, namely [Zn2(NH2bdc)(trz)2]n · 2n(e-urea) ( 1 ) and [Zn4(bdc)2(trz)4(H2O)(e-urea)]n · n(e-urea) ( 2 ) (Htrz = 1,2,4-triazole, NH2H2bdc = 2-aminoterephthalic acid, H2bdc = terephthalic acid, e-urea = 1,3-ethyleneurea). X-ray structural analyses revealed that both compounds 1 and 2 feature e-urea-templated 3D pillar-layer framework with 2D ZnII-triazole layer and 6-connected pcu topological network. These two compounds not only have high thermal stabilities but also show intense luminescence at room temperature. |
