Magnetic properties and electronic structure of CeTIn (T = Au, Ni) compounds with the hexagonal ZrNiAl-type structure have been investigated. CeAuIn is an antiferromagnet (T_N = 6.2 K) while CeNiIn was found to exhibit mixed valence and no magnetic ordering above 1.8 K. XPS measurements show that in CeNiIn the Ni 3d and Ce 4f states are both near the Fermi level. In CeAuIn only the Ce 4f state is near the Fermi level while the Au 5d band is represented by two peaks in the region between 3 and 7 eV below the Fermi level. The interpretation of Ce 3d XPS spectra in terms of the Gunnarsson--Schönhammer theory indicate that the hybridization energy \Delta between the Ce 4f and conduction band is equal to 144 meV for CeAuIn and 205 meV for CeNiIn.
