Coordination environment friendly silicon in copper(I) chloride π-complexes with tetravinylsilane and dimethyltetravinyldisiloxane

“…Secondly, a weakness of the third Cu-Cl bond may affect also the degree of self-assembly CuCl units. So none 2-D Cu n Cl n aggregate has been found in the olefin complexes with silicon ligands examined to date [41,13,14], and even the formation of 1-D motif here is complicated.…”

Highly stable olefin–Cu(i) coordination oligomers and polymers

“…[Cu 5 Cl 5 (Si(O-CH 2 -CHLCH 2 ) 4 ) ( 16) is the first reported example of a organo-silicon olefin-copper(I) coordination polymer prepared by reacting tetraallyloxysilane with CuCl. 15 In the structure, the tetraallyloxysilane ligand is tetradentate which gives a 4-fold axis passing through the Si atoms of the ligand. The four copper centers are linked by four Cl atoms to form an eight-membered ring and the remaining copper is connected to the four Cl atoms of the eight-membered ring and to a Cl in an axial position perpendicular to the plane of the eight-membered ring to give an approximately pyramidal coordination geometry (Fig.…”
