The title compound, C18H18N2O, was prepared by the reaction of 3-phenyl-1-( p-tol­yl)prop-2-en-1-one with hydrazine hydrate in acetic acid. The pyrazole ring is in an envelope conformation. The crystal packing is stabilized by van der Waals forces. [ABSTRACT FROM AUTHOR]

The title compound, C12H13NO2S, was prepared by the reaction of acetyl­acetone with phenyl isothio­cyanate. In addition to the intra­molecular O—H⋯O hydrogen bond, there is a weak inter­molecular N—H⋯S hydrogen bond, which links the mol­ecules into chains extended along the c axis. The crystal packing is further stabilized by van der Waals forces. [ABSTRACT FROM AUTHOR]

The title compound, C13H12N2OS, was prepared by the reaction of (4-pyrid­yl)methanol with phenyl isothio­cyanate and NaOH in a 1,4-dioxane solution. The asymmetric unit contains two independent mol­ecules. The mol­ecular structure and packing are stabilized by N—H⋯N inter­molecular hydrogen-bond inter­actions and C—H⋯π inter­actions.

p-Hydroxybenzoic acid (p-HOBA) was selected as the building block for self-assembly with five bases, i.e., diethylamine, tert-butylamine, cyclohexylamine, imidazole and piperazine, and generation of the corresponding acid-base complexes 1-5. Crystal structure analyses suggest that proton- -transfer from the carboxyl hydrogen to the nitrogen atom of the bases can be observed in 1-4, while only in 5 does a solvent water molecule co-exist with p- -HOBA and piperazine. With the presence of O-H…O hydrogen bonds in 1-4, the deprotonated p-hydroxybenzoate anions (p-HOBAA-) are simply connected each other in a head-to-tail motif to form one-dimensional (1D) arrays, which are further extended to distinct two-dimensional (2D) (for 1 and 4) and three-dimensional (3D) (for 2 and 3 ) networks via N-H…O interactions. While in 5, neutral acid and base are combined pair-wise by O-H…N and N-H…O bonds to form a 1D tape and then the 1D tapes are sequentially combined by water molecules to create a 3D network. Some interlayer or intralayer C-H…O, C-H…π and π …π interactions help to stabilize the supramolecular buildings. Melting point determination analyses indicate that the five acid-base complexes are not the ordinary superposition of the reactants and they are more stable than the original reactants.
