metal-organic compounds
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—HO interactions to form a three-dimensional network.
organic compounds
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.
organic compounds
The crystal structure of the centrosymmetric title compound, C24H48N4O84+·4Cl-·8H2O, consists of a 14-membered methyl-substituted C10N4 cationic ring which interacts with the chloride ions and water molecules of crystallization to give a three-dimensional hydrogen-bonded network structure.
