A wide domain of solid solutions have been prepared in the CrNbO4VO2MoO2 system with rutile-type structure. Electrical conductivity (77-300 K) and magnetic susceptibility (4.2-300 K) measurements of the samples show small band gap semiconducting behavior with very low activation energies (Ea < kT) and strong magnetic interactions of the metal ions, respectively. The magnitude of electrical conductivity and magnetic interactions increases with increasing Mo content. The transport properties are discussed in terms of the structural and electronic properties of the compounds. Results of lithium insertion reactions on selected compounds are also presented.
