✦ Synopsis
A new class of p-conjugated organic compounds, 1-aryl-2,5-bis[5-(tricyanoethenyl)-2-thienyl]pyrroles that form goldlike lustrous crystals with a high melting point were obtained. The molecules in these crystals are arranged in a planar sheet to get close to each other via the intermolecular C H•••N hydrogen bond between the cyano nitrogen and the hydrogen of the nearest thiophene or pyrrole ring, which makes the crystals sparingly soluble in common organic solvents.
