title: 5-Amino-3-eth-oxy-1,8,8-trimethyl-2-aza-bicyclo-[2.2.2]octa-2,5-diene-4,6-dicarbo-nitrile.
abstract: The title 2-aza-bicyclo-[2.2.2]octa-2,5-diene derivative, C(14)H(18)N(4)O, crystallized out with two independent mol-ecules with similar conformations in the asymmetric unit. In each mol-ecule, the three six-membered rings adopt boat conformations. The mol-ecules exist in the enamine form. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯N hydrogen bonds into a two-dimensional network parallel to the ab plane.
