摘要

报道了一种富锡异金属超分子产物[CuSn8(C5HF6O2)2(C5H2F6O4)4]或[Sn4(hfpt)2- cu (hfac)2-Sn4(hfpt)2] (I)的晶体结构(hfpt是1,1,1,5,5,5-六氟戊烷-2,2,4,4-四醇的阴离子，hfac是1,1,1,5,5,5-六氟戊烷-2,4-二酮的阴离子)。利用四酸锡(II) [Sn4(hfpt)2]与铜(II) β-二酮酸铜(Cu(hfac)2)的反应制备(I)。不对称单元由整个[Sn4(hfpt)2]单元和半个[Cu(hfac)2]单元组成，Cu原子位于反转中心。[Cu(hfac)2]中铜的轴向相互作用和[Sn4(hfpt)2]中hfpt配体的O原子之间的相互作用介导了(I)的夹层结构的形成。相邻[Sn4(hfpt)2]单元之间额外的分子间Sn·O相互作用完成了一个二维网络。

Bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato)tetrakis(μ4-1,1,1,5,5,5-hexafluoropentane-2,2,4,4-tetraolato)copper(II)octatin(II): a prospective precursor for Cu-doped SnO2 films.

The crystal structure of a tin-rich heterometallic supramolecular product, [CuSn8(C5HF6O2)2(C5H2F6O4)4] or [Sn4(hfpt)2-Cu(hfac)2-Sn4(hfpt)2], (I), is reported (hfpt is the tetraanion of 1,1,1,5,5,5-hexafluoropentane-2,2,4,4-tetraol and hfac is the anion of 1,1,1,5,5,5-hexafluoropentane-2,4-dione). Reaction between tin(II) tetraolate, [Sn4(hfpt)2], and copper(II) β-diketonate, [Cu(hfac)2], was utilized for the preparation of (I). The asymmetric unit consists of the whole [Sn4(hfpt)2] unit and half of a [Cu(hfac)2] unit, with the Cu atom lying on an inversion center. Intermolecular Cu···O interactions from the axial positions of copper in [Cu(hfac)2] and O atoms of the hfpt ligand in [Sn4(hfpt)2] mediate the formation of a sandwich-type structure for (I). Additional intermolecular Sn···O interactions between neighbouring [Sn4(hfpt)2] units complete a two-dimensional network.

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.
