The first silver(I) nitrate π-complexes with unsaturated organosilicons: Synthesis and structural characterization of [Ag(DADPS)xNO3] (DADPS = DIALLYLDIPHENYLSILANE (cas 10519-88-7), x = 0.75; 1)

Tetraethylene glycol dimethyl ether (tetraglyme) was used for the first time to induce the activation of silver nitrate resulting in the step-by-step formation of complexes with diallyldiphenylsilane (DADPS). Two crystal compounds of this series were examined by FTIR spectroscopy and X-ray diffraction. The analysis of the obtained data showed that the Ag(CC) η2-interaction is involved in the synergistic effect of intra and intermolecular forces. In particular the interlayer π–π stacking interactions promoted by asymmetric weak AgC(phenyl) bond have a significant influence on the thermal behavior and stability of the synthesized products. It was also found that a decrease of silver content is accompanied by a removal of aromatic ring from the coordination sphere of Ag(I) and respectively, by a reduction of complex stability.
