Abstract
We controlled [Ni(dmit)(2)](-) (S = 1/2) arrangements using a supramolecula r cation (SC) of 12-crown-4 including trivalent Sc3+ ion. The new crystal, Sc3+(12-crown-4)(2)[Ni(dmit)(2)](3)(CH3CN)(4), was composed of [Ni(dmit)(2) ](-) trimer and sandwich-type Sc3+(12-crown-4)(2). The magnetic susceptibil ity 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+(DA18-c rown-6)[Ni(dmit)(2)] and Ca2+(DA18-crown-6)[Ni(dmit)(2)](2)(CH3CN)(2) (DA18 -crown-6 = 1, 10-diaza-18-crown-6).
