Abstract:
Self-assembly of Ag(NO3)(2) with 5-sulfoisophthalic acid monosodium salt (NaH2SIP) in the presence of piperazine (pip) or 4,4'-bipyridyl (bpy) produced two new silver(I) coordination polymers, {(H(2)pip)(2)[Ag-8(SIP)(4)(H2O)(4)](H2O)(4)}(n) (1) and {[Ag(bpy)][Ag(HSIP)(bpy)](H2O)(2)}(n) (2), respectively. Single-crystal X-ray diffraction reveals that compound 1 has a 2D silver carboxylate-sulfonate layered structure containing an uncommon octanuclear [Ag-8(CO2)(8)] cluster wherein the eight silver(I) atoms form two intersecting Ag-4 planes. The 2D layers are further linked by the H(2)pip molecules through hydrogen bonds into a 3D supramolecular structure. Compound 2 features a 2D supramolecular network formed by silver(I)-bpy double chains and HSIP ligands through the combination of coordination bonds, ligand unsupported Ag center dot center dot center dot Ag interactions and weak Ag center dot center dot center dot O coordinative interactions. In the solid state at room temperature, compound 1 exhibits blue photoluminescence with a maximum at 450 nm upon excitation at 365 nm. Compound 2 shows green photoluminescence with a maximum at 564 nm upon excitation at 392 nm.
