The Preparation and Stability of Complex Compounds,uitous nature, water has most frequently been used as a solvent for preparing complex compounds. However, since all cations form some kind of bond with water molecules, it is not often appropriate to consider the water as an inert solvent that plays no part in the chemical reaction. For this reason

Electronic Spectra of Transition-metal Complexes,eater detail. The theory behind this material is difficult; in order that some progress can be made towards understanding the spectra and magnetism of complexes, it will be assumed that the student has some elenlentary knowledge of spectroscopic term symbols. Some of the more theoretical aspects of

Mechanisms of Complex-ion Reactions,tant may show that the equilibrium lies well over to the right-hand side. Those complexes for which equilibrium is attained rapidly, for example in less than one minute, are called . while those for which ligand substitution is a slow process are called .. These terms labile and inert are concerned

General Preparative Methods,e research scale. Occasionally the synthesis of a new compound has an enormous impact on our progress and understanding in chemistry. Such was the case with ferrocene Fe(π-C.H5).discovered in 1951, and xenon tetrafluoride XeF., first prepared in 1962.

Chromium, green colour of emeralds is due to the presence of chromium in the mineral beryl, and the colour of ruby is due to the substitution of Cr. ions for Al.ions in the structure of α-Al.0.. Chromium is the first element of group VI., lying above molybdenum and tungsten. The ground state outer electronic

Manganese, above technetium and rhenium. The maximum oxidation state +7 is shown in the permanganates, and all oxidation states from +7 to −3 are known; this is the widest range shown by a first-row transition element. Pure manganese is largely produced by electrolysis from aqueous solutions containing mangan
