“…In recent studies performed with these derivatives, the following properties have been reported: antitumor [24-29], cytotoxic [30], antibacterial [6,[31][32][33][34], antifungal [35,36], antiviral [37,38], antiparasitic [39][40][41], anti-inflammatory [42][43][44], analgesic [45][46][47], enzyme inhibition [48][49], antioxidant [50][51][52], antidiabetic [53], and anticonvulsant [54]. In coordination chemistry, acylhydrazones derived from isonicotohydrazine have been widely used as Schiff bases to synthesize stable complexes with transition metal or lanthanide ions [55][56][57]. In this paper, we report the synthesis, spectroscopic characterization, and crystal structure of a new complex [Co(HL)2]•Cl•3H2O derived from a Schiff base (H2L) obtained from a condensation reaction between isonicotinohydrazide and acetylpyridine in the presence of acetic acid.…”

A new Co(III) complex prepared by the reaction of N'–(1–(pyridin–2 yl)ethylidene) isonicotinohydrazide (H2L) with Co(II) ion is reported in this paper. The H2L ligand is structurally characterized by elemental analysis, NMR, and infrared spectroscopies. The mononuclear complex [Co(HL)2]·Cl·3H2O (1), is characterized by infrared spectroscopy, elemental analysis, conductance, magnetic room temperature measurement and single X-ray diffraction. The complex crystallizes in the monoclinic system with space group P21/c. The parameters of the unit cell are a = 9.6818(3) Å; b = 25.1587(6) Å; c = 11.5481(3) Å; β = 101.797(3) °; Z = 4; Rint = 0.0313 and wR(F2) = 0.0812. The asymmetric unit of the compound contains a discrete [Co(HL)2]+ cation one free chloride anion and three uncoordinated water molecules. In the discrete cation one Co3+ ion two organic ligand molecules are present. The coordination polyhedron around the Co3+ center is best described as a distorted octahedral with CoN4O2 chromophore. The crystal structure of the complex is stabilized by intramolecular and intermolecular hydrogen bonds.
