Two crystal complexes of copper(I) chloride with TETRAVINYLSILANE (cas 1112-55-6) (TVS) dimethyltetravinyldisiloxane (DMTVDS) were prepared and examined by IR spectroscopy and X-ray diffraction: sp. gr. P2/a, Z = 4, a = 13.428(1) Å, b = 7.9584(7) Å, c = 14.694(1) Å for [Cu4Cl4(TVS)]; sp. gr. P21/c, a = 10.505(1) Å, b = 13.487(1) Å, c = 13.870(1) Å for [Cu4Cl4(DMTVDS)]. The influence of the vinylsilicon ligands on the efficiency of the Cu⋯CC interaction is discussed. Thus, the consideration of dSi ← π∗CC ← dCu conjugate system may help to understand how the silicon π-acceptor properties influence on the degree of trigonal distortion of the Cu(I) coordination tetrahedron as well as on the inorganic part organization. The present studies are aimed at the use of the structure controlled nanoparticles supported on vinyl modified silicon (or silicone) substrate.
