TL;DR: In this paper, the first [2.2]paracyclophane bridged by heteroatoms has been prepared, which displays a strong σπ mixing between Si-Si bonds and aromatic rings as evidenced by a large red shift in UV spectra.
Abstract: 1,1,2,2,9,9,10,10-Octamethyl-1,2,9,10-tetrasila[2.2]paracyclophane, the first [2.2]paracyclophane bridged by heteroatoms, has been prepared. UV, IR, and 1H- 13C- and 29Si-NMR spectral together with X-ray crystallographic data are recorded. The compound displays a strong σπ mixing between Si–Si bonds and aromatic rings as evidenced by a large red shift in UV spectra.

TL;DR: The crystal structure of bis-1,2,5thiadiazolotetracyanoquinodimethane showed stacks of two-dimensionalally expanded sheet-like networks, in which the roughly coplanar molesules are connected to one another by way of the rhombohedral linkage involving short S-NC contacts of 3.03 A as discussed by the authors.
