Two novel homochiral enantiomers, trinuclear ionic clusters (NiL(1))(2)NaNCS(-).MeOH.Et(2)O (1) and (NiL(2))(2)NaNCS(-).MeOH.Et(2)O (2) [H(2)L(1) = N,N'-bis(3-methoxysalicylidene)-(1R,2R)-1,2-diphenylenediamine; H(2)L(2) = N,N'-bis(3-methoxysalicylidene)-(1S,2S)-1,2-diphenylenediamine], have been synthesized and structurally characterized. Both complexes have C(2) symmetry and crystallize in space group P2(1). Ferroelectric measurements reveal that complexes 1 and 2 represent a new type of ionic ferroelectric based on metal-organic coordination with a polarization value higher than that of KH(2)PO(4).
两种新型的手性对映异构体，三核离子簇(NiL(1))(2)NaNCS(-).MeOH.Et(2)O（1）和(NiL(2))(2)NaNCS(-).MeOH.Et(2)O（2）[H(2)L(1)=N,N'-双（3-甲氧基水杨醛基）-（1R,2R）-1,2-二苯二胺；H(2)L(2)=N,N'-双（3-甲氧基水杨醛基）-（1S,2S）-1,2-二苯二胺]，已经被合成并进行了结构表征。这两个配合物都具有 C(2)对称性，结晶于 P2(1)空间群中。铁电测量表明，配合物 1 和 2 代表了一种新型的基于金属有机配位的离子铁电体，其极化值高于 KH(2)PO(4)。
