Hydrogen-bonded sheets in 4-amino-8,8-dimethyl-2-(methylsulfanyl)-8,9- dihydro- Pyrimidino[4,5-b]quinolin-6(7H)-one

Abstract

The title molecule, C14H16N4OS, shows strong bond fixation within the fused heterocyclic rings. In the crystal structure, molecules are linked into sheets by a combination of N-H⋯N and N-H⋯O) hydrogen bonds. © 2006 International Union of Crystallography All rights reserved.
