5,5'-Methyl­enebis[6-amino-3-methyl-2-methyl­sulfanylpyrimidin-4(3H)-one]: an unusual mol­ecular geometry within a hydrogen-bonded mol­ecular ribbon

J. Trilleras, J. Ramos, J. Cobo and C. Glidewell

Synopsis: The central C-C-C angle is 120.3 (2)° and the mol­ecules are linked by N-H...O hydrogen bonds into a ribbon containing edge-fused S(8) and R_{4}^{2}(8) rings.

Formula: C13H18N6O2S2
