“…In order to model the active site structure of Mn-SOD, a novel manganese(II) complex [Mn 2 (ntb) 2 . This significant elongation has also been observed in other manganese complexes of tripodal tetradentate ligands with benzimidazolylmethyl group [3]. This complex can be regarded as the model complex of the active site structure of Mn-SOD.…”

“…Pyridinecarboxylic acids (picolinic, nicotinic and isonicotinic) are biologically important ligands incorporated into some enzymes, and they are active agents in some drugs as well [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In our previous work, we examined the effect of different metals (alkali [19][20][21], alkaline earth [22], 3d-metals [23]) on the electronic system of pyridinecarboxylic acids.…”

In this work, the thermal and spectroscopic properties of 3d-metal (Co, Cu, Zn, Mn, Ni, Fe) and sodium salts with cinchomeronic acid (3,4-pyridinedicarboxylic acid) (3,4pda) and dinicotinic acid (3,5-pyridinedicarboxylic acid) (3,5pda) were studied. The IR and Raman spectra were registered and analyzed in the range of 400-4000 cm -1 . The thermogravimetric study of synthesized compounds was done. The degree of hydration and the products of thermal decomposition were estimated. Moreover, it was done the comparison between the effect of 3d-transition metal cations and sodium cation on the degree of perturbation or stabilization of the electronic system of pyridine molecule depending on the position of carboxylic group in the ring.

Two nicotinate-containing cadmium(II) complexes were synthesized and structurally characterized. [Cd(ntb)(nic)]ClO 4 Á 0.5CH 3 OH (1) (ntb ¼ tris(2-benzimidazolylmethyl)amine, nic ¼ nicotinate anion) crystallized in the triclinic space group P-1 with a ¼ 13.9979 (17) The central Cd(II) is coordinated by four nitrogen atoms of ntb and two oxygen atoms of nicotinate to form a distorted octahedral geometry. [Cd(tren)(nic)]BPh 4 (2) (tren ¼ tris(2-aminoethyl) amine) crystallized in the monoclinic crystal system, P2 1 /c space group with a ¼ 18.610(6) Å , b ¼ 10.1620(16) Å , c ¼ 20.0085(18) Å and ¼ 111.230(11) . The central Cd(II) is coordinated by four nitrogen atoms of tren and one oxygen atom of nicotinate to form a distorted trigonal bipyramidal geometry. A tetramer for 1 and a dimer for 2 are formed through intermolecular hydrogen-bonding.
