Mercury Complexes Derived From Some Acetone Derivatives Ligands

Hg-2(II) and Hg(II)complexes with 1,3-diphenyl-1-ethanolimine-propylidin-3-one (HB1), 4-phenyl-2-ethanolimino-2-butylidine-4-one (HB2), 2-ethanolimino-2-pentylidin-4-one (HB3), and 2-(2-hydroxy-anilidino)-2-pentylidine-4-one (H2B4) as ligands were prepared and characterized by elemental analysis, electrical conductivity measurements, magnetic susceptibility determination, water content detection, mass, ir, uv/vis spectroscopy, and thermogravimetry. The formed complexes can be formulated as [Hg-2(B-n)(2)(H2O)(m)] and [Hg(B-n)(H2O)(m)]center dot NO3 (where n = 1, 2, 3 or 4) with two exception, one of them for Hg-2(II)-H2B4, has [Hg-2(HB4)(2)(H2O)(m)] formula and the other for Hg(II)-H2B4, has [Hg(B-4)(H2O)(m)] formula. The conductivity of 0.001M of the complexes in DMSO reveal of the ionizable nature of one nitrate group for mercury(II) complexes meanwhile Hg(II)-B-4 and mercury(I) complexes act as non-electrolyte solution. The thermalgravimetric studies and also the water content accounting reveal the coordinated nature of the water molecules rather than the crystalline nature. The magnetic susceptibility determination shows the ferromagnetic behavior of the formed complexes. Molecular mechanical calculation (MM2) and molecular modeling were carried out on the coordination sphere of the synthesized complexes
