Two new azo-containing Schiff bases and their transition metal complexes were synthesized. Single-crystal X-ray analyses were performed on the ligand (L1H) and complex (Zn(L1)2). The synthesized metal complexes were used as catalysts for the chemical fixation of CO2 into cyclic carbonates. The azo moiety increased the activity.

Oxidation of [Fe(CO)2(′N2H2S2′')] (1) (′N2H2S2'2- = 1,2-ethanediamine-N,N′-bis(2-benzenethiolate)(2—)) gave insoluble [Fe(′N2S2')]2 (2) ('N2S2'2- = glyoxal-bis(2-mercaptoanil)(2—)). Dinuclear, thiolato-bridged 2 was characterized by single crystal X-ray structure analysis. It does not react with CO or H2, but yields bis or mono adducts with PR3 (R = Me, n-Bu, Cy).

Two Schiff base ligands Ampp-Sn1and Bmpp-Sn2, afforded by a condensation reaction between sulfanilamide and the respective acylpyrazolone carbonyl precursors, their Mn(II), Co(II), Ni(II), and Cu(II) complexes prepared by the reaction of ligands and corresponding metal salts in aqueous solutions, were synthesized and then characterized by both analytical and spectroscopic methods, in a view to developing new improved bioactive materials with novel properties. On the basis of elemental analysis, spectroscopic and TGA results, transition metal complexes, with octahedral geometry having two molecules of the bidentate keto-imine ligand each, have been proposed. The single crystal structure of Bmpp-Sn according to X-ray crystallography showed a keto-imine tautomer type of Schiff base, having three intramolecular bonds, one short N2⋯H2⋯O3 hydrogen bond of 1.90 Å and two long C13⋯H13⋯O2 and C32⋯H32⋯O3 hydrogen bonds of 2.48 Å. A moderate to low biological activities have been exhibited by synthesized compounds when compared with standard antimicrobial agents on screening the synthesized compounds againstStaphylococcus aureus,Bacillus pumilus,Proteus vulgaris, andAeromonas hydrophilafor antibacterial activity and against free radical 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) for antioxidant activity.

: The catalytic activity of Schiff base Co(II), Ni(II), Cu(II) and Zn(II) transition metal complexes were tested for N-Acylation of heterocycles with acetyl chloride. It is observed that all the complexes worked as the efficient catalysts. The Structural type of the complexes were studied by X-ray powder diffractogram (XRD). The mixed ligand complexes with PPh3 ligand show greater activity as compared to Phen complexes and Schiff base complexes. Especially complex [Ni(L)(PPh3)2Cl2] efficiently worked as catalyst because of high thermal stability (TGA-DSC) and large catalytic surface area (BET).

Structure Investigations

The syntheses and structure investigations of four new 3d transition metal complexes (1–4) with a flexible N4O2-donor hexadentate Schiff-base ligand are described; three complexes (1, 2, and 4) of FeIII, CoIII, and CuII metal ions have been investigated by UV-vis, FT-IR, high-resolution mass spectrometry (HR-MS), and scanning electron microscopy–electron dispersive spectroscopy, as well as single crystal X-ray diffraction. The X-ray structure of NiII complex 3 is also reported. The molecular structures of the complexes (1–3) demonstrate distorted octahedral coordination geometry, each exhibiting 1 : 1 (M : L) ratios and the CuII complex 4 shows a trinuclear structure with a CuII : L ratio of 3 : 2 in the solid state, which has been proven by X-ray diffraction. On the other hand, a mononuclear species of the CuII complex is formed in solution, which has been identified by electrospray ionization HR-MS.
