UCo4B is a member of uranium intermetallic borides family which crystallizes in the hexagonal CeCo4B structure. The experimental data suggest the occurrence of the spin-fluctuation behaviour of UCo4B. In this paper we present the results of band structure calculations using the ab-initio tight binding linear muffin-tin orbital method. We found good agreement between the experimental X-ray photoemission spectroscopy valence band spectrum and the ab-initio results.
