“…A large number of hexa-coordinated Ni II complexes have been investigated magnetically and a magneto-structural correlation related to D was established based on the magnetic properties of a wide range of complexes with tetragonal bipyramidal geometries. This correlation demonstrated that the ZFS parameter D evolves more or less linearly with the structural tetragonality, with an enhanced negative D value for a tetragonally (highly) compressed geometry [83,108,200,209,210]. The ZFS parameters D for these complexes range from -8 cm -1 to 8 cm -1 [83].…”

“…Synthesis, spectroscopic and magnetic properties, and crystal structures of some copper(II), cobalt(II) and nickel(II) complexes with furopyridine and its derivatives as ligands have been reported in previous articles [12][13][14][15][16][17][18]. The furopyridines in all structures of the complexes are monodentate nitrogen donor ligands.…”

The synthesis and characterization of six new 2-methylthionicotinate (2-MeSnic) copper(II) monomeric complexes [Cu(2-MeSnic) 2 L 2 ] (L is furo[3,2-c]pyridinefpy, 2-methylfuro[3,2-c]pyridine-Mefpy, 2,3-dimethylfuro-[3,2-c]pyridine-Me 2 fpy or benzo[4,5]furo[3,2-c]pyridineBfp), [Cu(2-MeSnic) 2 (fpy) 2 (H 2 O)], as well as [Cu(2-MeSnic) 2 (CF 3 Phfpy) 2 (H 2 O) 2 ] (CF 3 Phfpy is 2-(3-trifluoromethylphenyl)furo[3,2-c]pyridine) are reported. The characterizations were based on elemental analysis, infrared, electronic and EPR spectra. The crystal structure of one of the complexes has been determined. The Cu II atoms of [Cu(2-MeSnic) 2 (fpy) 2 (H 2 O)] are six-coordinated in a highly distorted tetragonal-bipyramidal arrangement by two nitrogen atoms, one from each fpy, in trans-positions, by three oxygen atoms of the carboxyl groups of 2-MeSnic ligands (one monodentate, one asymmetrically bidentate), one axial position being occupied by the oxygen of a water molecule. The antimicrobial effects have been tested on various strains of bacteria, yeasts and filamentous fungi. A comparison of the IC 50 and MIC values has shown a decrease of inhibition activities of tested compounds in the order: [Cu(2-MeSnic) 2 (Bfp) 2 ] [ Bfp [ [Cu(2-MeSnic) 2 (CF 3 Phfpy) 2 (H 2 O) 2 ] [ [Cu-(2-MeSnic) 2 (Me 2 fpy) 2 ] [ CF 3 Phfpy [ [Cu(2-MeSnic) 2 (Mefpy) 2 ] [ Me 2 fpy [ [Cu(2-MeSnic) 2 (fpy) 2 (H 2 O)] [ [Cu(2-MeSnic) 2 (H 2 O)] 2 [ Mefpy [ fpy = 2-MeSnicH = CuSO 4 .

“…The coordination chemistry of them has already been outlined (MIKLOVIČ et al, 2004;BARAN et al, 2005). However, systematic studies need much more effort, and in addition to the structural features also the spectral and magnetic data would be interesting.…”

Thieno[3,2-c]pyridine (thpy) has been prepared in a free form and embodied into the [Ni(thpy) 2 (H 2 O) 2 (ac) 2 ] complex as a ligand. The X-ray structure shows a molecular structure of the complex with Ni−O(ac) = 2.059, Ni−OH 2 = 2.078, and Ni−N(thpy) = 2.124 Ǻ. Electronically the complex behaves like a compressed tetragonal bipyramid. The molecular units are linked into a complex system of hydrogen bonds. Two units show a π−π stacking of the aromatic rings (3.8 Ǻ). There are planes of tetragons formed of the nickel atom with the in-plane Ni...Ni separation of 7.74 Ǻ and the inter-plane Ni...Ni contacts at a = 9.65 Ǻ. The effective magnetic moment shows a gradual decrease on cooling from the room temperature and an abrupt drop below 20 K typical for the zero-field splitting of S = 1 systems. Above the room temperature the effective magnetic moment shows anomalies -a decrease and then an increase.
