Electrochemical and chemical oxidations of Mo(CNPh)6 and W(CNPh)6 have been shown to yield seven-coordinate [M(CNPh)7]2+. These catons, stabilized as their PF6− salts, can be obtained in yields of 80%. The redox and substitution chemistry of these new complexes have been explored. A convenient synthesis of W(CNPh)6 has been devised starting from W2(dmhp)4 (dmhp is the anion of 2,4-dimethyl-6-hydroxypyrimidine)
