Abstract

We controlled [Ni(dmit) 2] - (S = 1/2) arrangements using a supramolecular cation (SC) of 12-crown-4 including trivalent Sc 3+ ion. The new crystal, Sc 3+(12-crown-4) 2[Ni(dmit) 2] 3 (CH 3CN) 4, was composed of [Ni(dmit) 2] - trimer and sandwich-type Sc 3+(12-crown-4) 2. The magnetic susceptibility per trimer unit was 0.35 emu·K·mol -1, which showed Curie paramagnetic temperature dependence. The details of the structure and magnetic behavior are discussed in comparison with monovalent and divalent salts, Rb +(DAlS-crown-6)[Ni(dmit) 2] and Ca 2+(DA18-crown-6)[Ni(dmit) 2] 2 (CH 3CN) 2 (DA18-crown-6 = 1,10-diaza- 18-crown-6).
