Highly crystalline CaTaN 2 was prepared by the reaction of Ca(NH 2 ) 2 and Ta 3 N 5 in a specially designed reaction vessel at high temperatures (> 1300°C). Even when reaction conditions varied considerably, the samples were always contaminated by small amounts of Ca 2 TaN 3 , TaN, or TaN 0 . 1 . SQUID measurements obtained on a sample contaminated by Ca 2 TaN 3 and a sample contaminated by TaN and TaN 0 . 1 showed superconducting transitions at 9.6 K and 9.1 K, respectively. Resistivity measurements carried out on a sintered pellet of CaTaN 2 contaminated by TaN 0 . 1 showed a ρ(300 K) = 0.0147 ωcm and weakly rising resistivity with lower temperatures, likely due to the random alignment of the polycrystalline grains.
