摘要

通过[Cu(II)2(O2CCF3)4]的双丙酮加合物和[Cu(I)4(O2CCF3)4]的亲电性很强的四核配合物[Cu(I)4(O2CCF3)4]共沉积，制备了双价超分子产物[Cu10(C2F3O2)12(c3h60)2]或{[Cu(I)4(O2CCF3)4]2-{μ2-OC(CH3)2}2-[Cu(II)2(O2CCF3)4]}。不对称单元包含一个化合物分子和总共十个独立的Cu原子。丙酮分子在[Cu(II)2(O2CCF3)4]和[Cu(I)4(O2CCF3)4]单元之间起桥梁作用。此外，四铜(I)三氟乙酸酯单元参与分子间Cu···O相互作用，在扩展结构中形成层状二维网络。

Building a two-dimensional network from mixed-valence copper units held together by acetone bridges.

The mixed-valence supramolecular product di-μ2-acetone-di-μ3-trifluoroacetato-deca-μ2-trifluoroacetato-octacopper(I)dicopper(II), [Cu10(C2F3O2)12(C3H6O)2] or {[Cu(I)4(O2CCF3)4]2-{μ2-OC(CH3)2}2-[Cu(II)2(O2CCF3)4]}, was prepared by co-deposition of two building units, namely a bis-acetone adduct of [Cu(II)2(O2CCF3)4] and a very electrophilic tetranuclear [Cu(I)4(O2CCF3)4] complex. The asymmetric unit contains one molecule of the compound with a total of ten independent Cu atoms. Acetone molecules serve as bridges between the [Cu(II)2(O2CCF3)4] and [Cu(I)4(O2CCF3)4] units. Additionally, the tetracopper(I) trifluoroacetate units are involved in intermolecular Cu···O interactions, forming a layered two-dimensional network in the extended structure.

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.
