9-(1,1-Dimethyl-3-oxobut-yl)adenine.


ABSTRACT: The title compound, C(11)H(15)N(5)O, crystallizes with two independent mol-ecules in the asymmetric unit, both of which contain essentially planar imidazole and pyrimidine rings [maximum deviations = 0.002?(2) and 0.026?(2)?Å, respectively, for the first mol-ecule, and 0.001?(2) and 0.025?(2)?Å for the second]; the dihedral angles between the rings are 2.1?(2) and 1.7?(2)° in the two mol-ecules. The crystal structure is stabilized by inter-molecular N-H?N hydrogen bonds, defining chains along a, which are further linked by weak inter-molecular ?-? contacts [centroid centroid distance = 3.7989?(16)?Å] into planes parallel to (01).

The title compound, C(11)H(15)N(5)O, crystallizes with two independent mol-ecules in the asymmetric unit, both of which contain essentially planar imidazole and pyrimidine rings [maximum deviations = 0.002 (2) and 0.026 (2) Å, respectively, for the first mol-ecule, and 0.001 (2) and 0.025 (2) Å for the second]; the dihedral angles between the rings are 2.1 (2) and 1.7 (2)° in the two mol-ecules.
