Abstract
Nicotinamide has been employed as a supramolecular reagent in the synthesis of ten copper(II) chloro-, bromo-, fluoro-, iodo-, and dichlorobenzoate complexes. Compound structures were determined by single-crystal X-ray diffraction structural analysis. All ten compounds are monomeric complexes with a square-bipyramidal coordination sphere around the Cu2+ ion. The two polymorphs of [Cu(2,6-Cl(2)bz)(2)(nia)(2)] are examples of coordination compounds which are conformation and supramolecular isomers. The molecules of all compounds are connected by N-HaEuro broken vertical bar O and O-HaEuro broken vertical bar O hydrogen bonds from NH2 groups of nicotinamide and water molecules which create supramolecular hydrogen-bonding-coordination chains and networks.
