Abstract The preparations of two precursors (Bu4N)[Cr(NAOP)(NCS)2] (1) and (Bu4N)[Cr(SALEN)(NCS)2] · CH3OH (2) (NAOP2− = N,N′-(1,2-phenylenebis(nitrilomethylidyne))bis(2-naphtholate), SALEN2− = N,N′-ethylenebis(salicylideneiminate)), and X-ray crystal structures and magnetic properties of four new charge transfer salts with organo-sulphur donor molecules [TTF][Cr(NAOP)(NCS)2] (3), [BEDT-TTF][Cr(NAOP)(NCS)2] · 1
摘要两种前体(Bu4N)[Cr(NAOP)(NCS)2](1)和(Bu4N)[Cr(SALEN)(NCS)2]·CH3OH(2)的制备(NAOP2--= N,N'- (1,2-亚苯基双(亚硝基甲基亚炔))双(2-萘甲酸酯),SALEN2--N,N'-亚乙基双(水杨亚胺),以及四种新型有机硫电荷转移盐的X射线晶体结构和磁性供体分子[TTF] [Cr(NAOP)(NCS)2](3),[BEDT-TTF] [Cr(NAOP)(NCS)2]·1.5CH2Cl2(4),(HMET)[Cr(NAOP)(描述了[NCS)2]·2.5CH 2 Cl 2(5)和[TTF] 3 [Cr(SALEN)(NCS)2] 3·4CH 2 Cl 2·H 2 O(6)。所有的电荷转移盐在施主和阴离子之间都有许多短的S⋯S接触,但是在它们之间没有检测到磁性交换。根据超分子组织讨论了远距离磁序的存在:结构中没有阳离子和阴离子
