In each molecule, the three six-membered rings adopt boat conformations. The molecules exist in the enamine form. In the crystal, molecules are linked by N¡ªH...O and N¡ªH...N hydrogen bonds into a two-dimensional network parallel to the ab plane. %U http://scripts.iucr.org/cgi-bin/paper?S1600536812032990
