Three trinuclear Mn2Mo molecules based on the orbitally degenerate Mo(CN)7 anion were prepared, one of which is the first single-molecule magnet (SMM) based on heptacyanomolybdate. The blocking temperature and the energy barrier (U = 40.5 cm(-1)) are records for a cyanide-based SMM. Wide hysteresis loops and sharp quantum tunneling steps were observed from single-crystal measurements.
制备了三个基于轨道简并的Mo(CN)7阴离子的三核 Mn2Mo 分子,其中一个是基于七氰合钼酸盐的首个单分子磁体(SMM)。其阻塞温度和能垒(U = 40.5 cm(-1))创下了基于氰化物的 SMM 的纪录。从单晶测量中观察到了宽的滞后回线和尖锐的量子隧穿阶。
