7′-Amino-1′H-spiro­[cyclo­heptane-1,2′-pyrimido[4,5-d]pyrimidin]-4′(3′H)-one

The title compound, C(12)H(17)N(5)O, was obtained by cyclo­condensation of 2,4-diamino­pyrimidine-5-carbonitrile with cyclo­hepta­none. The tetra­hydro­pyrimidine ring has a dis­torted boat conformation and the cyclo­heptane ring adopts a chair conformation. In the crystal, molecules are linked via...

description The title compound, C(12)H(17)N(5)O, was obtained by cyclo­condensation of 2,4-diamino­pyrimidine-5-carbonitrile with cyclo­hepta­none. The tetra­hydro­pyrimidine ring has a dis­torted boat conformation and the cyclo­heptane ring adopts a chair conformation. In the crystal, molecules are linked via N—H⋯O and N—H⋯N hydrogen bonds generating a three-dimensional network.
