Silica-Organometallic One-Dimensional Hybrid Employing a Ag-πC═C Bond Connecting Alternating Ag4(NO3)4 and Octavinylsilsesquioxane.

Layering AgNO3 in alcohol onto octavinylsilsesquioxane (OVS) in CHCl3 results in a one-dimensional coordination polymer, {Ag4(NO3)4(OVS)·solvents}n (SD/Ag4a-d), consisting of unprecedented flat weakly bonded Ag4(NO3)4 alternating with the firmly covalent OVS through AgI-πC═C bonds. The preferential assembling medium for SD/Ag4a is proven to be alcohols, where a 4:1 silver-OVS adduct is detected by electrospray ionization mass spectrometry. The present outcomes may assist our knowledge of particular interactions for supramolecular architectures of a polynuclear silver system built from OVS containing eight pendent olefin tails.
