The adducts methylthiourea:1,4-dioxane (2:1) (1) and 1,1-dimethylthiourea:morpholine (1:1) (2) were prepared and their crystal structures determined In 1, hydrogen bonding involving the methylthiourea mols. leads to the formation of R22(8) rings and thence to mol. ribbons parallel to [110]. The dioxane mols. accept hydrogen bonds from the remaining NH groups, and their inversion symmetry means that they connect adjacent methylthiourea ribbons, forming a layer structure parallel to (11?1). In the packing of 2, dimethylthiourea dimers cannot link to each other because of the blocking effect of their Me groups, but instead are linked indirectly via morpholine mols., the NH groups of which are simultaneously hydrogen bond acceptors from the remaining NH function of dimethylthiourea and donors towards the sulfur atom of a neighboring dimer. The overall effect is to form broad ribbons parallel to the a axis, with the morpholine mols. occupying the peripheral positions. The morpholine oxygen atom of 2 is not involved in classical hydrogen bonds.
