Structural and optical profile of a multifunctionalized 2-pyridone derivative in a crystal engineering perspective.

The supramolecular structural features of organic molecules are very important with regard to their widespread properties in both solids and solutions. Herein, we describe the synthesis of a novel multifunctional 2-pyridone derivative, namely 6-(4-chlorophenyl)-5-formyl-4-methylsulfanyl-2-oxo-1,2-dihydropyridine-3-carbonitrile, CHClNOS, denoted P1, and its structural features were established through X-ray crystallography. A Hirshfeld surface analysis followed by a two-dimensional fingerprint plot analysis was carried out.

2-[2-Benzoyl-3,3-bis-(methyl-sulfan-yl)prop-2-enyl-idene]malononitrile.

The title compound, C(15)H(12)N(2)OS(2), is an example of a push-pull butadiene in which the electron-releasing methyl-sulfanyl groups and electron-withdrawing nitrile groups on either end of the butadiene chain enhance the conjugation in the system. Short intra-molecular C-H⋯S inter-actions are observed. In the crystal structure, an O⋯C short contact of 2.

2-[2-(4-Methyl-benzo-yl)-3,3-bis-(methyl-sulfan-yl)prop-2-enyl-idene]malononitrile.

The title compound, C(16)H(14)N(2)OS(2), is an example of a push-pull butadiene in which the electron-releasing and electron-withdrawing attachments on either end of the butadiene chain enhance the conjugation in the system. The mol-ecules are linked by inter-molecular C-H⋯N inter-actions.
