| Abstract: | The title complex {[Ag(HPPz)4(NO3)](NO3)4}, 1, has been prepared from the reaction of trans-2-(2-phenylethenyl)pyrazine (PPz) with AgNO3 at room temperature in 10% HNO3 and structurally determined by single-crystal X-ray diffraction analysis. The result shows that the AgI center is five-coordinated with one anion and four mono-protonated HPPz+ ligands. The anions display versatility not only participating in coordination, but also linking the HPPz+ ligands by electrostatic and hydrogen bond interactions. The final framework can be considered as a 3D supramolecular architecture built up by the self-assembly of the building blocks ([Ag(HPPz)4(NO3)]3+, ), driven by diverse interactions based on the anions. |
