Abstract

Complexes of copper(II) with 2-(acetylamino)benzoic acid, 2-(benzoylamino) benzoic acid, 2-(aminocarbonyl)benzoic acid, 2-[(phenylamino)carbonyl]benzoic acid, 2-[(1-naphthalenylamino)carbonyl]benzoic acid, 2-[(2-aminophenylamino)carbonyl]benzoic acid, 2-aminobenzanilide, 2(aminobenzoyl)benzoic acid, maleanilic acid and malea-1-naphthalanilic acid have been prepared and characterized by chemical analyses, molar conductivity, magnetic susceptibility measurements, thermal data, IR, electronic and ESR spectra. The visible and ESR spectral studies of these complexes (except those of maleanilic acid and malea-1-naphthalanilic acid) indicate that they are monomeric having either square planar or distorted octahedral geometry around Cu(II). The Cu(II) complexes of maleanilic acid and malea-1-naphthalanilic acid have been tentatively assigned dimeric structures. From the ESR spectra of Cu(II) complexes various parameters have been calculated.

      In a previous work authors reported significant spectral differences in carbamoyl benzoic acids as function of the substituent in the amide which leads to an increase or decrease in electron delocalization, as well as fluorescence intensity [10]. Moreover, photophysical studies of various heavy metals in the presence of carbamoyl acids showed its potential application in the detection and separation of metal ions in aqueous media [14,15]. Coagulation-flocculation process is appropriate for pollutants removal.

      There are many samples of the in vivo interplay of transition metals with the amide groups and these interplays may have biological significance [4–6]. These compounds are widely used in fields of science including industrial, pharmacological and biological studies [7,8]. Sarıoğlu et al. [9] carried out a DFT based computational study to investigate the results of a caboxamide derivative compound on the molecular computation, NMR chemical shift, vibrational spectroscopic properties, and antimicrobial and antifungal activity.

      They also show a strong antifungal activity [16] or they may act as inhibitors against aldose reductase [17]. The complexes of Tl(I), Sn(IV), Mo(IV) and Co(II) ions with maleinic acid and the compounds of Cu(II) ion with its various amido derivatives were prepared and characterized [18–24]. The thermodynamics functions for the formation of complexes of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) ions with maleanilic, 4-nitro- and 4-methoxymaleanilic acids were determined [25].

      Pyridine carboxamide compounds containing common carboxamide [–C(O)NH–] group in the main structure of proteins are important for construction of metal complexes [2]. These compounds are widely used in the many fields of science such as industrial, pharmacological and biological studies [3,4]. The literature concerning the dibenzoyl acetic acid compounds with nitrophenyl amide is rich and the papers published cover such subjects as synthesize [5], NMR and vibrational characteristics [6,7].
