Transport properties and magnetization measurements of the K x MoO 2−␦ ͑0 Յ x Յ 0.25͒ compound are reported. The compound crystallizes in the oxygen deficient MoO 2 monoclinic structure with potassium atoms occupying interstitial positions. An unconventional metallic behavior with power-law temperature dependence is related to a magnetic ordering. Superconducting transition with small volume fraction is also observed near 7 K for a sample with low potassium composition.
