    Abstract: Two oxalate compounds [(C4H7N2)3][Sb(C2O4)3] (1) and [(Et3NH)][SnPhCl(C2O4)2] (2), have been isolated and characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system, space group P21/c with a=13.3944 (6) Å, b=11.3554 (5) Å, c=16.3314 (7) Å, β=107.206 (1), V=2372.82 (18) Å3 and Z=4. Compound 2 crystallizes in ...

    Abstract: The method of ESR is widely used for the investigation of electronic construction and the geometrical structure of the polynuclear complexes of the transition metals. The majority of the well-known experimental works had been done using monocrystals and polycrystalline examples. Construction of mononuclear complexes of the copper(II), the nature of... Show More

    Abstract: Schiff base (L) ligand is prepared via condensation of P-Anisaldehyde and ethylene diamine in 2:1 ratio in ethanol. A new complex is prepared by reacting this ligand with metallic salt CdI2. The structure of the two derivatives are confirmed using various spectroscopic techniques: C, H, N analyses, IR, UV-visible and X-ray diffraction. The IR spect... Show More
