Cadmium complexes pyridine oxide

Recently Zn NMR studies of imidazole and carboxylate complexes and the thermolysin-zinc complex have been described and Cd NMR studies of a wide range of complexes have been reported CdNMR data for pyridine adducts of Cd /3-diketonates show the influence of the sulfur and nitrogen donors on the chemical shift Cadmium NMR studies on cadmium fluoride have also been reported. A CdNMR study of Cd-enriched phosphine oxide complexes has been reported " and a multinuclear NMR investigation and Cd) of cadmium dithiophosphate complexes has been described. ... 

The complexes, [Fe(py>4]X2 (X = Br, 1), have been prepared by oxidation of metallic iron with bromine or iodine in methanol. Pyridine is added to the resultant solution and the pyridine complexes precipitated.22 Interaction between metallic zinc or cadmium and an excess of arsenic pentafluoride in liquid sulfur dioxide leads to the formation of solvento-complexes containing two or four SO2 ligands depending on the experimental conditions.23/24 The reactions studied are summarized as follows, Eq.4.4 ...
