N,N′-Bis[2,6-bis(1-methylethyl)phenyl]pyridine-4-carboximidamide toluene hemisolvate

Abstract

The title compound, C30H39N3·0.5C7H8, is a symmetrically N,N′-disubstituted arylamidine containing a 4-pyridyl substituent on the carbon atom of the N–C–N linkage and bulky 2,6-diisopropylphenyl groups on the nitrogen atoms. It crystallizes in the Z-anti configuration and its amidine C—N bonds present amine [1.368 (1) Å] and imine [1.286 (1) Å] features. Intramolecular hydrogen bonds are present in the structure together with intermolecular N—H...N and C—H...N interactions linking the molecules in chains along the a- and c-axis directions.
