We present a study of the local environment of the Co atom in single crystalline Co{sub x}NbSe{sub 2}, x = 0.013, via Extended X-ray Absorption Fine Structure (EXAFS) measurements at the Co K-edge (7.7 keV) at various temperatures. Co intercalation quickly suppresses superconductivity and the charge-density wave (CDW) present in pure NbSe{sub 2}. In order to study the effect of impurities on superconducting and CDW states one has to verify the random distribution of the intercalated atoms in contrast to possible clustering which could lead to additional, e.g. magnetic, interactions in the case of Co intercalation. Our measurements show that the Co atoms are indeed randomly distributed in Co{sub 0.013}NbSe{sub 2}.
