intermolecular contacts in 1·MeOH and 1 reveals no significant hydrogen bonding between the dinuclear units, while in 2·MeOH these units are held together by significant hydrogen bonds between one of the uncoordinated nitrile groups and the anilate function, giving rise to 1D supramolecular structure. The three dinuclear complexes 1, 2·MeOH, and 2 exhibit SCO behaviors which have been evidenced by the thermal
旋交叉(SCO)的Fe(II)式的双核配合物的[Fe 2(TMPA)2(μ 2 -tcpd)2 ]·0.8(CH 3 OH)(1·MeOH中)和[铁2(andmpa)2( μ 2 -tcpd)2 ]·2CH 3 OH(2·MeOH中)(TMPA =三(2-吡啶基甲基)胺,andmpa =双(2-吡啶基甲基)氨基甲基)苯胺,(TCPD)2- = 2二氰基亚甲基1 (1,3,3-四氰基丙二胺)已被合成并通过红外光谱,X射线衍射和磁测量进行表征。两种配合物(1·MeOH和2·MeOH中)和去溶剂化的复杂1(从1·MeOH中)揭示了中性中心对称双核结构,其中(TCPD)2- cyanocarbanion充当双μ 2 2 [FEL]之间-bridging配体2+(L = TMPA (1)和(2))单元涉及两个自由的顺式构型位点。在1·MeOH和1中检测最短的分子间接触表明,在2·MeOH中双核单元之
