Complex of Cadmium(II) Iodide with 3,4-Diphenyl-1-(Pyridin-2-yl)-6,7-Dihydro-5H-Cyclopenta[c]pyridine: Synthesis and X-ray Diffraction Study

The structure of the cadmium(II) iodide complex with 3,4-diphenyl-1-(pyridin-2-yl)-6,7-dihydro-5 H -cyclopenta[ c ]pyridine is studied and determined by X-ray diffraction analysis (СIF file CCDC no. 1833097). The problem about the possibility of coordination of the phenyl substituents of the ligands to the central cadmium atom is examined. The degree of participation of the π system of the phenyl substituent of the ligand in the coordination to the central ion is analyzed using quantum chemical calculations.
