The title compound, C11H12O3, was synthesized from 4-hydr­oxy-3-methoxy­benzaldehyde and acetone. The mol­ecule has a high degree of conjugation throughout the system and inter­molecular hydrogen bonds connect adjacent mol­ecules to form one-dimensional chains.

The title compound, C13H16N2O3, was synthesized from vanillin, acetone and hydrazine monohydrate. An inter­molecular O—H⋯O hydrogen bond connects the mol­ecules into infinite one-dimensional chains.

The Co atom in the title compound, [Co(C20H38N4O4)]·4H2O, is chelated by the four N atoms of the macrocycle and also covalently bonded to two carboxyl­ate O atoms in a cis-N4O2Co octa­hedral environment. The mononuclear mol­ecule inter­acts with the non-coordinated water mol­ecules by way of O—H⋯O inter­actions to form a three-dimensional network.

The title compound, (E)-4-(2-hydroxy­phenyl)­but-3-en-2-one, C10H10O2, was synthesized from salicyl­aldehyde and acetone. The mol­ecule is essentially planar, suggesting a high degree of conjugation throughout the system. Intermolecular hydrogen bonds link adjacent mol­ecules to form one-dimensional chains.

The title compound, C24H46N4O82+·2Cl−·2H2O, was synthesized by the hydrolysis of tetraethyl 2,2′,2′′,2′′′-(5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetrayl) tetraacetate in hydrochloric acid solution. The crystal structure of the title compound consists of a 14-membered C10N4 centrosymmetric cationic macrocycle which interacts with the chloride ions and water molecules of crystallization to give a three-dimensional hydrogen-bonded network.
