Bis[N-(4-carboxyphenyl)phtalimidyl]dimethylsilane is prepared and used to build novel hydrogen-bonded supramolecular polymers as a result of co-crystallization with pyridine derivatives: 4,40-bipyridyl (SP1), 1,2-bis(4-pyridyl)ethylene (SP2), and 4,40-azopyridine (SP3), as presented on page 3775 by M.-F. Zaltariov, M. Cazacu, S. Shova, A. Vlad, I. Stoica, and E. Hamciuc. The figure shows a fragment of the 3D two-component supramolecular architecture in the crystal structure of SP3 that arises from the extended system of OAH˙˙˙N and CAH˙˙˙O hydrogen bonds. The 3D packing in the SP3 structure essentially results from the parallel packing of the wavy layers in (011) orientation.
