“…(Lah 2006) All other complexes including carboxylato complexes exhibit Cu : hmpy ratio 1 : 2. As an example we could point out recently published methyl-and methoxysalicylatocopper complexes with 2-hydroxymethylpyridine of the formula [Cu(XSal) 2 (hmpy) 2 ] where XSal = 3-methylsalicylate, 4-methylsalicylate or 5-methylsalicylate anion or 3-methoxylsalicylate or 4-methoxylsalicylate anion) (Repická 2012).…”

As a part of our systematic study of copper(II) complexes in presence of biologically active ligands, we concluded to realize experiments with methyl- or methoxysalicylatocopper(II) complexes in presence of 2-aminomethylpyridine (ampy) ligand. This has resulted in four new complexes of the formula Cu(XSal)2(ampy) (where XSal are 3-MeSal− = 3-methylsalicylate, 4-MeSal− = 4-methylsalicylate, 5-MeSal− = 5-methylsalicylate, or 4-MeOSal− = 4-methoxylsalicylate anions). The synthesis, elemental analysis and spectral properties (EPR, electronic and infrared) are reported. The Cu(II) atom in all four complexes is probably coordinated by two nitrogen atom of the bidentate chelating ampy as well as monodentate and/or highly asymmetrically chelating salicylate anions. Based on the analyses it was concluded that the structure of these new compounds could be similar to [Cu(HCOO)2(ampy)], or [Cu(CH3COO)2(ampy)] that are reported in the literature.

Salicylate anions offer a wider range of bonding modes from the most common monodentate (Icbudak et al, 2003;Devereuxe et al, 2007;Repická et al, 2012;Mirzaei et al, 2012), through bidentate-chelating (Mirzaei et al, 2012;Gembicky et al, 2008) and bridging (Mei et al, 2010), to chelating-bridging (Mukherjee et al, 2012;Palanisami et al, 2006). This paper is focused on the preparation and spectral properties of 5-nitrosalicylatocopper(II) and 3,5-dinitrosalicylatocopper(II) complexes with 2-(aminomethyl)pyridine and/or 2-(hydroxymethyl) pyridine.…”

Three new nitrosalicylatocopper(II) complexes have been prepared and characterized. Compounds of the composition Cu(5-NSal)2(2-ampy)2 (1), Cu(5-NSal)2(2-hmpy)2 (2) and Cu(3,5-DNSal)2(2-hmpy)2 (3), where 2-ampy = (2-aminomethyl)pyridine, 2-hmpy = (2-hydroxymethyl)pyridine, 5-NSal = 5-nitrosalicylate anion and 3,5-DNSal = 3,5-dinitrosalicylate anion, were characterized by elemental analyses, EPR and IR spectroscopy. EPR spectra are consistent with the dx2-y2ground electronic state. Spectral properties have shown “classic” monodentate coordination of 5-nitrosalicylate anion. Similarly, bonding mode of the 3,5‑dinitrosalicylate anion in (3) is assumed to be unidentate via the carboxyl group, which is surprising compared with the previously studied complex, where the preferred coordination via the phenolate group anion was observed.
