Self-assembly hydrogen-bonded supramolecular arrays from copper(II) halogenobenzoates with nicotinamide: Structure and EPR spectra

Popis výsledku v původním jazyce

Nicotinamide was employed as a supramolecular reagent in the synthesis of six new copper(II) bromo-, iodo-, fluoro-and dibromobenzoate complexes. Structures of [Cu(2-Brbz)(2)(nia)(2)(H2O)(2)] (I), [Cu(2-Ibz)(2)(nia)(2)(H2O)(2)] (II), [Cu(2-Fbz)(2)(nia)(2)(H2O)(2)] (III), [Cu(4-Brbz)(2)(nia)(2)(H2O)(2)] (IV), [Cu(3,5-Br(2)bz)(2)(nia)(2)(H2O)(2)] (V), [Cu(F-Fbz)(2)(nia)(2)(H2O)] center dot H2O (VI) (nia = nicotinamide, 2-Brbz = 2-bromobenzoate, 4-Brbz = 4-bromobenzoate, 3,5-Br(2)bz = 3,5-dibromobenzoate, 2-Ibz = 2-iodobenzoate, 2-Fbz = 2-fluorobenzoate, 4-Fbz = 4-fluorobenzoate) were determined using X-ray analysis. Compound [Cu(2-Brbz)(2)(nia)(2)] center dot 2H(2)O (VII) was prepared by a new method and also characterized by X-ray powder diffraction and EPR spectroscopy. Compounds I-V are monomeric complexes with a square-bipyramidal coordination sphere around the Cu2+ ion. Complex VI is monomeric with coordination environment around the Cu2+ ion of a tetragonal-pyramid. Complexes I and VII present examples of coordination isomerism. Molecules of all compounds are connected by N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds from the NH2 groups of nicotinamide and water molecules which create supramolecular hydrogen-bonding-coordination chains and networks.
