(Received November 30, 1995)

Hexagonal potassium cobalt oxide KCo₂O₄, with lattice parameters of a=2.846 Å and
c=12.417 Å, has been prepared using KCO₃ and Co₃O₄ as starting materials. The specimens show metallic conduction, with almost linear decrease in the resistivity, in the order of 10^-2 Ω·cm, down to 12 K. The magnetic susceptibility is of the order of 10^-6 emu/g and shows paramagnetic behavior. ©1996 The Physical Society of Japan
