Synthesis and characterisation of [HGX2.l1-10]x complexes with macrocyclic ligands: An photoelectron spectroscopic study

Abstract

A complex compound is an entity consisting of two or more molecular species, which interact in such manner that they are being held together in a physically characterisable structural relationship. Macrocyclic and macopolycyclic effects designate the great thermodynamic stability of macrocyclic ligand complexes compared to non- macrocyclic analogues. The design of novel macrocyclic ligands and their complexes is interesting in view of their use as models to elaborate the metal ions interaction and to get an insight of the coordinating sites in metalloprotiens and in biological system. Hg(II) complexes of the type [HgX2L1-10]X, where X=Cl or NO3; L= macrocyclic ligands derived from C6H5COCOC6H5 (2mmol) condensation with different aliphatic diamine (2mmol) have been synthesized and characterized by elemental analysis, molar conductance, IR spectra and X-ray photoelectron i.e. (XPS) spectra. An octahedral geometry is also established for each complex.
