Deskripsi
The title compound, C20H20N4O, is packed into a three-dimensional `herringbone' matrix using two different types of attractive C—H...N(cyano) interactions. The bond-length alternation, caused by delocalization of charge between the donor N atoms and the cyano acceptor groups, is compared with related compounds.
