title: 7-Amino-2-tert-butyl-5-methylpyrazolo[1,5-a]pyrimidine: a three-dimensional framework structure built from two N-H...N hydrogen bonds.
abstract: The bond distances in the title compound, C11H16N4, provide evidence for peripheral delocalization of pi electrons. The molecules are linked by two independent N-H...N hydrogen bonds into a three-dimensional framework structure.
