“…The broadening of the signal might be due to Jahn–Teller distortion. The absorption bands of the diffuse electronic spectra and value of their magnetic moment favor a tetragonally distorted octahedral geometry around Cu(II) ion 43–45. [Ni(K) 2 (H 2 O) 2 ] showed three weak absorption bands at 9974, 16013 and 24464 cm −1 corresponding to the characteristic transitions 3 A 2g → 3 T 2g , 3 A 2g → 3 T 1g (F), 3 A 2g → 3 T 1g (P).…”

1 H NMR, 13 C NMR and IR spectroscopic techniques and reacted with transition metal salts to afford metalcontaining heterochelates. The structures of the synthesized heterochelates were characterized using elemental analyses, infrared spectra, electronic spectra, magnetic measurements, FAB mass spectrum and thermogravimetric analyses. The kinetic parameters such as order of reaction (n) and the energy of activation (E a ) are reported using the Freeman-Carroll method. The pre-exponential factor (A), the activation entropy ( S # ), the activation enthalpy ( H # ) and the free energy of activation ( G # ) were calculated. Heterochelates were also screened for their in vitro antibacterial activity against a range of Gram-positive (Bacillus substilis, Staphylococcus aureus) and Gram-negative (Escherichia coli, Serratiamarcescens) organisms.

New ethylenebismaleimide-diamine oligoimide-II (EBMDDMCMHQ) containing 8-hydroxyquinoline as a pendent group(s) was prepared using ethylenebismaleimidediamine oligoimide-I (EBMDDM) and 5-chloromethyl-8-hydroxyquinoline hydrochloride (CMHQ) in the presence of base catalyst. Ethylenebismaleimide-diamine oligoimide-I (EBMDDM) was prepared by the Michael addition reaction of ethylenebismaleimide (EBM) and 4,4 0 -diaminodiphenyl methane (DDM). The resulting oligoimide-II (EBMDDMCMHQ) was characterized by spectral techniques. Polymeric metal chelates of oligoimide-II were prepared using transition metal ions and were duly characterized. Ion-exchange properties of oligoimide-II for Fe(III), Zn(II), Ni(II), and Cu(II) metal ions were also studied by batch-equilibration method. It has good metal ion uptake capacity at varying pH ranges.

A series of 10 novel 5-bromo-thiophene containing chalcone derivatives (SN1-SN10) were synthesized under ultrasonic irradiation in the presence of lithium hydroxide monohydrate (LiOH.H 2 O) as a catalyst, which provided the products in good yields after short reaction times under mild conditions. All the synthesized compounds were characterized by spectral data and evaluated for in vitro antibacterial and antifungal activities. Antibacterial and antifungal activities were tested using the agar diffusion method. From the screening studies it was observed that most of the compounds have shown moderate antibacterial and antifungal activities at 500 µg/mL and 100 μg/mL concentrations respectively. Test compounds SN4, SN6, SN7 and SN8 exhibited promising antibacterial activity at 500 µg/mL concentration against the standard ciprofloxacin, whereas all the tested compounds are less active against Candida albicans and moderately active against Aspergillus niger when compared to that of the standard fluconazole.
