Abstract
The structures of six triperiodic CuCN network structures with conjugate acids of four N-alkylethanolamines as guest cations are described, namely, poly[2-hydroxyethan-1-aminium [μ3-cyanido-di-μ2-cyanido-dicuprate(I)]], {(C2H8NO)[Cu2(CN)3]}n, 1, poly[bis(2-hydroxy-N-methylethan-1-aminium) [di-μ3-cyanido-tri-μ2-cyanido-tricuprate(I)] monohydrate], {(C4H12NO)2[Cu3(CN)5]·H2O}n, 2, poly[tetrakis[N-(2-hydroxyethyl)ethan-1-aminium] [chloridotetra-μ3-cyanido-penta-μ2-cyanido-tricuprate(I)]], {(C4H12NO)4[Cu6(CN)9Cl]}n, 3, poly[tetrakis[N-(2-hydroxyethyl)ethan-1-aminium] [penta-μ3-cyanido-hepta-μ2-cyanido-octacuprate(I)]], {(C4H12NO)4[Cu8(CN)12]}n, 4, poly[2-hydroxy-N,N-diisopropylethan-1-aminium [μ3-cyanido-μ2-cyanido-dicuprate(I)] monohydrate], {(C8H20NO)[Cu3(CN)4]·H2O}n, 5, and poly[2-hydroxy-N,N-diisopropylethan-1-aminium [μ3-cyanido-di-μ2-cyanido-dicuprate(I)]], {(C8H20NO)[Cu2(CN)3]}n, 6. In five of the structures (1-5), the CuCN network includes Cu atoms occurring in pairs, linked by cuprophilic interactions. Analysis with the intent of exploring the `template effect' of the cations on the CuCN network structure indicated five separate CuCN topologies. The two different crystal structures involving cations from N-ethylethanolamine have the same basic topology, whereas the two crystal structures involving cations from N,N-diisopropylethanolamine have different topologies, contrary to what might be expected from a template effect. Thermogravimetric analysis of the compounds usually shows loss of HCN(g) and the free base by 200 °C, with a CuCN(s) residue, but decomposition of one of the structures is more complex.
期刊介绍：
Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
