title: Crystal structure of methyl 4-(2-fluoro-phenyl)-6-methyl-2-sulfanylidene-1,2,3,4-tetra-hydro-pyrimidine-5-carb-oxy-late.
abstract: In the title compound, C13H13FN2O2S, the pyrimidine ring adopts a twist-boat conformation with the MeCN and methine-C atoms displaced by 0.0938 (6) and 0.2739 (3) Å, respectively, from the mean plane through the other four atoms of the ring. The 2-fluoro-benzene ring is positioned axially and forms a dihedral angle of 89.13 (4)° with the mean plane through the pyrimidine ring. The crystal structure features N-H⋯O, N-H⋯S and C-H⋯O hydrogen bonds that link mol-ecules into supra-molecular chains along the b axis. These chains are linked into a layer parallel to (10-1) by C-H⋯π inter-actions; layers stack with no specific inter-actions between them.
