Source of material

The educt N′-acetyl-5-chloro-2-hydroxybenzohydrazide (LH3), intended to be the bridging ligand in its deprotonated form was synthesized according to reference [4]. A mixture of LH3 (0.196 g, 1 mmol) and nickel acetate (0.162 g, 1 mmol) and a few drops of a NaOH solution in 10 ml methanol was stirred at room temperature for 1 h. The mixture was filtered to remove impurties, and then left at room temperature. After a few days, red blocks of the ligand were formed. Yield (0.23 g, 60%).

Experimental details

H atoms were geometrically placed (C—H = 0.95–0.98 Å) and refined as riding with Uiso(H) = 1.2–1.5 Ueq(C) [3].

Comment

Pentadentate ligands have been synthesized in recent years [5]. Pentadentate ligands can react with the transition metals and rare earth metals [6], [, 7]. A lot of the ring structure containing complexes and metallacrown complexes have been synthesized. In recent years, our group synthesized several pentadentate ligands, the ligand L/LH3 is one of them. The new ligand reacts with the transition metals [8].

As shown in the Figure, the title compound crystallizes in the monoclinic space group P21/c with four formula units in the unit cell. The bond lengths of Ni–O are 2.030, 2.000, 2.035, 2.003 and 2.049 Å, the bond lengths of Ni–N are 2.081, 2.091, 2.165, 2.174, 1.976, 2.105, 2.211, 2.215, 1.978, 2.108, 2.193 and 2.198 Å, respectively, the bond lengths of Ni–N from the pyridine molecule is longer than the bond lengths of Ni–N from the anionic ligands, which are similar with the reference [8]. The trinuclear complex is almost centrosymmetric but this symmetry is not supported by the crystallographic findings. The Ni complex is formed by two chelated ligands three nickel ions and eight pyridine molecules. We can see that each nickel ion resides in a slightly distorted octahedral coordination environment, consisting of three pyridine N, a phenolate O, a carbonyl oxido O and an imine-type nitrogen of L, which construct the five-membered and six-membered rings with each nickel atom.
