Polymer complexes: supramolecular modeling for determination and identification of the bond lengths in novel polymer complexes from their infrared spectra

Abstract

Synthesis and characterization of allyl propenyl-2-(4-derivatives phenylazo)butan-3-one (HLThe bond distances of these complexes were also investigated. The effect of Hamett's constant is also discussed.

Evaluation and Rearrangement of Novel Supramolecular 7-(2,3-dihydro- 1,3-benzothiazol-2-yl)quinolin-8-ol Complexes and their Biological Effect

“…The ESR spectrum of solid Cu(II) complex at room temperature is characteristic of a monomer, d 9 , configuration. The ESR spectrum shows g ll >g ┴ >2.0023, suggesting a d x2-y2 ground state, which is characteristic of a tetrahedral geometry [24].…”

“…Studies of the complexing ability and analytical applications of heterocyclic azomethines derived from thiazoline compounds are very important [7][8][9]. It is well known that some drugs have increased activity when administered as metal complexes and a number of metal chelates inhibit tumor growth [10].…”

“…The band at 290-340 cm À1 is assigned to the (M-Cl) vibration. [16,[30][31][32]. The UO bond distance is in the usual range (1.60-1.92 Å ) observed for dioxouranium(VI) complexes [16,[30][31][32].…”

“…[16,[30][31][32]. The UO bond distance is in the usual range (1.60-1.92 Å ) observed for dioxouranium(VI) complexes [16,[30][31][32]. The uranyl polymeric complex displays bands at 1638 and 1348 cm À1 due to symmetric and asymmetric stretching vibrations of the acetate group [15] with D ¼ 290 cm À1 characteristic for monodentate acetate.…”
