Ethyl (4-benzyl­oxyphen­yl)-6-methyl-2-sulfanyl­idene-1,2,3,4-tetra­hydro­pyrimidine-5-carboxyl­ate and a redetermination of ethyl (4RS)-4-(4-meth­oxy­phen­yl)-6-methyl-2-sulfanyl­idene-1,2,3,4-tetra­hydro­pyrimidine-5-carboxyl­ate, as its 0.105-hydrate, both at 200 K: subtly different hydrogen-bonded ribbons

Figure 3
A stereoview of part of the crystal structure of compound (III), showing the formation of a hydrogen-bonded ribbon parallel to the [001] direction containing two types of centrosymmetric R₂²(8) ring and a single type of R₄⁴(20) ring, which is noncentrosymmetric. Hydrogen bonds are shown as dashed lines and, for the sake of clarity, H atoms bonded to C atoms have been omitted.
