Preparation, Structure and Reactions

EPR studies of Cs2[TcNX5j in HX (X = C1, Br) solution and of AsPh4-[TCNX4] in organic solvents in the presence of a large molar ratio of X- show no evidence for the equilibria [126] 

These results indicate that the form in HX solution is most likely [TcN(OH2)X4], with the trans ligand readily lost or exchanged, and the form precipitated de-

The history of these elements and their few compounds dominates this chapter. We start with the usual treatment of the discovery and isolation of the elements, followed by a much shorter than normal section on periodic properties and the network. Given that the actual chemistry of this group is dominated by xenon, the third section is devoted almost entirely to the preparation, structure, and reactions of its compounds. A short section on the practical importance of the elements is followed by the selected topic in depth, the carcinogenic threat of radon.
