Abstract

The title compound, C₃₀H₃₉N₃·0.5C₇H₈, is a symmetrically N,N'-disubstituted aryl-amidine containing a 4-pyridyl substituent on the carbon atom of the N-C-N linkage and bulky 2,6-diiso-propyl-phenyl groups on the nitro-gen 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. Intra-molecular hydrogen bonds are present in the structure together with inter-molecular N-H⋯N and C-H⋯N inter-actions linking the mol-ecules in chains along the a- and c-axis directions.

Keywords: bulky arylamidine; crystal structure; hydrogen bonding.
