An orthorhombic series of alkali ammonia trivalent fulleride compounds were synthesized. It was found that the antiferromagnetic transition exhibits a systematic change against the interfullerene spacing. Overall, the results indicate that the ammoniation emphasizes the electron correlation effect possibly via crystal symmetry reduction.
