A new interstitial nitride Ce3(Fe0.95Ti0.05)29N4 with Nd3(Fe,Ti)29-type structure has been synthesized. The X-ray pattern can be indexed according to the monoclinic space group A2/m and the unit cell dimensions are a=10.866(7) Å, b=8.755(6) Å, c=9.924(7) Å, β=97.39(2)° and V=936.23 Å3. The relative lattice expansion upon nitrogenation is 8%. The Curie temperature TC is 670 K and the saturation magnetization MS is 1.22 at 5 K and 1.15 MA/m at 300 K. The anisotropy field HA is 2.67 at 5 K and 1.65 MA/m at 300 K and the average hyperfine field is 32.5 T at 85 K and 29.6 T at 293 K. Both the parent and the nitrided compounds exhibit a complex type of magnetocrystalline anisotropy
