在甲醇中，[Mn(5-Clsalen)(H2O)]ClO4与[K(18-冠-6)(H2O)2]3[Fe(CN)6]反应生成复盐[K(18-crown)(MeOH)2][Mn(5-Clsalen)(H2O)(MeOH)]2[Fe(CN)6]·4MeOH 1[5-Clsalen=N，N‘-亚乙基(5-氯水杨酸亚胺)，18-冠-6=1，4，7，10，13，16-六氧基环十八烷]。化合物1属单斜晶系C2/c空间群，晶胞参数为a=29.065(5)，b=14.261(8)，c=18.443(6)A，β=98.83(2)°，Z_0=0.04，V_3=0.7553(4)A_3。两个[Mn(5-Clsalen)(H2O)(MeOH)]+阳离子和[Fe(CN)6]3-阴离子通过Mn-OH2·H2O·Nc-Fe和Mn-MeOH·H2O·Nc-Fe键氢键形成二维网络结构，前者的O··N间距为2.768(8)A，后者为2.684(8)A。[K(18-冠-6)(MeOH)2]+阳离子位于二维层之间。化合物1在空气中部分解溶得到[K(18-冠-6)][Mn(5-Clsalen)(H2O)]2[Fe(CN)6]1‘，由于局部形成磁耦合亚晶格而表现出短程磁相互作用。化合物1‘通过加热到180℃完全脱溶，得到[K(18-冠-6)][Mn(5-Clsalen)]2[Fe(CN)6]2，由于形成了一个由Mn-NC-Fe键延伸到整个晶格的网络，该化合物表现出自发磁化作用。
The reaction of [Mn(5-Clsalen)(H2O)]ClO4 with [K(18-crown-6)(H2O)2]3[Fe(CN)6] in methanol gave a double salt, [K(18-crown)(MeOH)2][Mn(5-Clsalen)(H2O)(MeOH)]2[Fe(CN)6]·4MeOH 1 [5-Clsalen = N,N′-ethylenebis(5-chlorosalicylideneiminate), 18-crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadecane]. Compound 1 crystallizes in the monoclinic space group C2/c with cell dimensions of a = 29.065(5), b = 14.261(8), c = 18.443(6) A, β = 98.83(2)°, Z = 4, V = 7553(4) A3. The two [Mn(5-Clsalen)(H2O)(MeOH)]+ cations and the [Fe(CN)6]3– anion are hydrogen bonded, through the Mn–OH2· · ·NC–Fe and Mn–MeOH· · ·NC–Fe linkages, to form a two-dimensional network structure; the O· · ·N separation is 2.768(8) A in the former linkage and 2.684(8) A in the latter. The [K(18-crown-6)(MeOH)2]+ cations are situated between the two-dimensional layers. Compound 1 was partially desolvated in air to give [K(18-crown-6)][Mn(5-Clsalen)(H2O)]2[Fe(CN)6] 1′ which exhibited a short range magnetic interaction due to the local formation of magnetically coupled sublattices. Compound 1′ was fully desolvated by heating to 180 °C to give [K(18-crown-6)][Mn(5-Clsalen)]2[Fe(CN)6] 2 which exhibited spontaneous magnetization due to the formation of a network extended by Mn–NC–Fe linkages throughout the lattice.
