The valence states and thermoelectric properties of two Ru-based uranium ternaries, namely U2Ru2Sn and U2RuGa8, have been studied. Intermediate-valence behaviour manifests themselves in broad peaks in the susceptibility, largely negative values of the paramagnetic Curie temperature and in the occurrence of maxima in the thermoelectric power. At the same time the specific heat data show no transition at low temperatures for both the compounds studied. The experimental results are fitted to the equations given in the literature relevant to a valence fluctuating state. The studied compounds are unique examples of such a state found for the first time among the huge family of known up to know uranium compounds usually being magnetically ordered at low temperatures.
