“…The Cu-N bond lengths for bidentate tmen in [Cu(tmen)(salH)2] (Cu-N(2)= 2.020 (9), Cu-N(1)= 2.040 (10) Å), and Cu(1)-N(1A) 2.017(7) and Cu(1)-N(2A)= 2.034(13) Å for 2 are comparable. The bite angles (N(I)--Cu-N(2) 86.9 (4)˚ for[37] and N(1A)-Cu(1)-N(2A)= 86.5(3) for 2) are also similar in both complexes.…”

Two copper(II) coordination complexes, formulated as [Cu(tmen)(ClBA)2] (1) and [Cu(tmen)(Hsal)2.H2O] (2), (where tmen = N,N,N′,N′-tetramethylethylenediamine (C6H16N2), ClBA = 2-chlorobenzoate (C7H4ClO2 1-) and Hsal 1-(C7H5O3 1-) = monoanion of o-hydroxybenzoic acid (salicylic acid), have been synthesized and characterized by elemental combustion analysis, spectroscopic techniques, thermal studies and single crystal X-ray analyses. The complex (1) consists of two distinct monomeric units in which coordination environment around the central copper(II) ion is a distorted octahedron with CuN2O4 chromophore, constituted by; a chelating tmen molecule, and two 2-chlorobenzoate 1anions coordinated through their carboxylate-O atoms in an asymmetrical bidentate fashion. The complex (2), is also a monomer and consists of CuN2O3 chromophore, in which tmen is coordinated to Cu(II) through its two N atoms in a chelating bidentate fashion, an aqua-O and the two o-hydroxybenzoate 1-(HSal 1-) anions coordinated through one of their carboxylate-O atoms in a monodentate mode, forming a square pyramidal structure. Hydrogen bonding interactions especially of O-HO, N-HO, and C-HCl types interweave monomeric units and stabilize the overall crystal structures in both complexes. Thermal analysis and antibacterial activities of 1 and 2, against various bacterial strains are also investigated.

Polymerization of 2,4,6-trichlorophenol (TCPH) was achieved through the thermal decomposition of the copper and cobalt complexes of TCPH with N-containing ligands [N-methyl imidazole (NMIz) and 3,5-dimethyl pyrazole (DMPz)]. The structural analysis of the complexes was performed by using Fourier transform infrared (FTIR), differential scanning calorimetry (DSC), mass (MS), UV-VIS, diffuse reflectance (DRS) and electron spin resonance (ESR) spectroscopies, magnetic susceptibility balance and elemental analyses. Polymerization was achieved either in solid state or in melt, and the polymers were characterized by FTIR, nuclear magnetic resonance (NMR) spectroscopy, DSC, and viscosity measurements. The effects of the temperature and time dependencies of %Conversion on polymer synthesis were investigated. The cobalt complexes (having higher decomposition temperatures) were more stable than copper complexes (decomposing at lower temperatures). Thermal stability with respect to N-ligand shows that the complexes with NMIz are more stable than DMPz complexes of the same metal. The highest molecular weights (M w ) were achieved at the end of 3 hr of polymerization for C1 at 1708C, C2 at 1208C, and C4 at 1508C. The longer time at lowest conversion leads to highest M w of C1 at 1258C at the end of 24 hr, C2 at 908C at the end of 72 hr and at 1008C at the end of 48 hr.The M w of the polymeric products range between 8.5 Â 10 3 and 6.5 Â 10 4 . All polymers are rigid and have branched structures.
