Synthesis and Characterization of Palladium(II) Complexes with 2-(2'-hydroxylphenyl)benzoxazole, 2-(2'-hydroxyl phenyl)benzothiazole or the Mixed Ligands

Synthesis and Characterization of Pd(II) And Pt(II) Complexes with Bis [Hg (2-Apt)] Compound.

“…The bands of (C-N) and (C-S) shifted to 1543 and 758cm -1 respectively, these shifting to a lower and higher frequency from the compound indicated coordination of nitrogen and sulfur to metal ions of Pd(II) and Pt(II) [12]. The new bands at 570-420cm -1 which are supported the coordination of metal ions with N and S atoms (M-N), (M-S) [13], Table 2. The UV-Vis spectrum in 10 -3 M DMSO shows three transitions of Pd(II) complex ,at 21739 cm -1 , 27027 cm -1 , and 29411 cm -1 which are due to to the 1 A 1 g→ 1 A 2 g , 1 A 1 g→ 1 Eg and charge transfer respectively, these transitions are indicated to square planner geometry [14].…”

“…CHNS analysis in (Al-ALBayt) University Central Labs (Jordon). 1 H-NMR, 13 C-NMR spectra of complexes were carried on Bruker ultra shield 300 MHz with TMS as internal reference, in (Al-ALBayt) University Central Labs (Jordon), using DMSO-d6 as a solvent. Conductivity measurements were carried out on a Jenway conductivity meter 4200 (093 cell constant) (UK.).…”

“…The 1 H-NMR, 13 C-NMR spectra of compound [Hg (2-apt)] in DMSO-d6 solvent . All protons were seen according to the expected chemical shift, the 1 H-NMR which appeared at (δ= 6.4-7.4)ppm for (4H) proton of [Hg(2-apt)] compound [5].…”
