Abstract:
Two complexes of isonitrosoacetylacetone-N-arylimine, PdCl(C6H5-IAI) (C6H5NH2) (1) and PdCl (p-CH3C6H4-IAI) (p-CH3C6H4NH2) (2), were synthesized and characterized by IR and Raman spectroscopy. Complex 1 crystallizes in orthorhombic system, space group Pca21, with parameters a=1. 858 7(4) nm, b=0. 938 0(2) nm, c=2. 123 7(4) nm, V=3. 702(1) nm3, Dc=1. 572 g/cm3, Z= 8, F(000)=1 760, μ=1. 160 mm-1. The final R1 value is 0. 027 1 for 3 592 observed reflections with I≥2σf(I). The Pd(double-struck I sign) ion has a distorted square-planar PdN3Cl coordination composed of imino-nitrogen and oximo-nitrogen from the Schiff base ligand, amino-nitrogen from aniline and chlorine anion. The oxime group of the Schiff base ligand is coordinated to the Pd(double-struck I sign) through its oximo-nitrogen atom, but not its oximo-oxygen atom. The νC=O and νC=N bands display a shift to lower frequencies and νN-O bands to higher frequencies in IR and Raman spectra. There are π-π* transition and d-π* charge-transfer transition in electronic spectra.
