Metathesis Reactions of the super-Prussian Blue Systems [(Me3Sn)3M(CN)6] (M=Co, Ir) with, inter alia, Tetrapropylammonium (and -phosphonium) Ions: Crystal Structures of [(nPr4P)(Me3Sn)2Co(CN)6·2H2O] and [(nPr4N)(Me3Sn)2Ir(CN)6·2H2O]

The single-crystal X-ray structures of 1a-P (E=P; M=Co) and 3a (E=N; M=Ir) document new examples of either modification. While Me4N+ and Et4N+ ions do not form sufficiently insoluble, R4N+-containing assemblies, nBu4N+ and nPen4N+ give rise to similar (i.e., R4N:Me3Sn=1:2) products as nPr4N+. The slightly modified super-Prussian blue system [Me2Sn(CH2)3SnMe2}1.5Co(CN)6], 4, reacts with nPr4NBr to yield
四丙基铵和-磷离子n Pr 4 E +容易与聚合的超-普鲁士蓝衍生物[(Me 3 Sn)3 M(CN)6 ](M = Co,Ir)反应,后者由无限的[ – M –CN–Sn–NC–]链,提供双态超分子组装体[(n Pr 4 E)(Me 3 Sn)2 M(CN)6 ·2H 2 O]。后一种类型的所有代表都没有任何扩展[– M–CN–Sn–NC–]骨干。1a-P(E = P; M = Co)和3a(E = N ; M = Ir)的单晶X射线结构记录了这两种修改的新示例。尽管Me 4 N +和Et 4 N +离子不能形成足够的不溶性,但含R 4 N +的组装体,n Bu 4 N +和n Pen 4 N +产生相似的离子(即R 4 N:Me 3 Sn = 1:2)产品为nPr 4 N +。略加修饰的超普鲁士蓝体系[Me 2 Sn(CH 2)3 SnMe 2 } 1.5 Co(CN)6 ],4,与n
