Here, we report a low\u2010coordination praseodymium (Pr) complex, namely, Pr@C\n                    <jats:sub>81<\/jats:sub>\n                    N, featuring a non\u2010Kramers trivalent Pr ion entrapped within an azafullerene cage and behaving as the first Pr\u2010based SMM. Although the weak nonaxial ligand field imposed only by the carbon cage on the integer\u2010spin Pr(III) elicits nondegenerate spin states, Pr@C\n                    <jats:sub>81<\/jats:sub>\n                    N shows an anomalous magnetic hysteresis up to 20\u00a0K using a field sweep rate of 20\u00a0Oe\/s, which is the highest temperature among all reported light\u2010Ln SMMs. In addition to the ideally minimized spin\u2013phonon coupling in the low coordination, the origin of such an unexpected magnetic bistability for the non\u2010Kramers complex likely lies in nuclear sublevels arising from a large Pr hyperfine coupling, which feature distinct electronic magnetizations within the highly mixed ground electronic state.\n
