L e v y 2b Department of Chemistry, New York University (Z. Naturforschg. 21 b, 823— 827 [1966] ; eingegangen am 9. Mai 1966) A proximity effect in arene ^-complex formation from the reaction system of an aryl G r i g n a r d reagent and anhydrous chromic chloride was investigated. The yields of arene ^-complexes and any accompanying reaction products were compared by the systematic variation of the aryl G r i

properties such as electrical resistivity and the magnetic susceptibility. In order to certify this complex formation in liquid Pb–Te alloy, we are also studying the thermodynamic properties of this system, based on a model of the mixture of covalent molecules of PbTe and metallic part of Pb–Te binary alloys [ 5 ]. Since both the electronic behavior and the thermodynamic one in liquid Pb–Te binary alloys have therefore strongly indicated the covalent-type formation of PbTe molecule, we have to clarify the existing evidence of this formation from the structural information

11 Complex formation 11.1 Introduction Metal ions in aqueous systems are able to react with other dissolved species (mol- ecules or ions) to form distinct entities that are referred to as complexes (or more precisely coordination complexes). These complexes are typically readily soluble and their formation has a strong impact on the behavior of the metal ions in other reac- tions, such as acid/base, precipitation/dissolution or redox processes. This impact on other reaction equilibria makes complex formation significant for aqueous systems. Since complex
