The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

Research paper thumbnail of Synthesis and characterization of new 2-pyrimidyl chalcogen (S, Se, Te) compounds: X-ray crystal structure of bis(4,6-dimethyl-2-pyrimidyl)diselenide and 4,6-dimethyl-2-(phenylselanyl)pyrimidine

The unsymmetrical 4,6-dimethyl-2-(arylchalcogenyl)pyrimidines have also been prepared by reacting 4,6-dimethyl-2-chloropyrimidine with the arylselenide ion, ArSe À (Ar ¼ phenyl, naphthyl, p-tolyl, 4-chloro-2-pyrimidyl). All the newly synthesized compounds have been thoroughly characterized with the help of various spectroscopic techniques viz., NMR (1 H, 13 C, 77 Se), FT-IR and mass spectrometry (in representative cases). The crystal structures of bis(4,6-dimethyl-2-pyrimidyl)diselenide and 4,6-dimethyl-2-(phenylselanyl)pyrimidine have been determined by X-ray crystallography.
