摘要

报告了通过单晶 X 射线衍射测定的三碳酰基[η4-6-外-(三苯基膦)环-庚-2,4-二烯-1-酮]铁(0)四氟硼酸二-氯甲烷半溶液[Fe(C28H22O4)(CO)3]BF4-0.5CH2Cl2 的分子结构。两个独立的三碳基[η4-6-外-（三苯基膦）环庚-2,4-二烯-1-酮]铁（0）阳离子及其相应的阴离子形成二聚体，构成了平行于（100）平面的结构不对称单元。C-H⋯O 和 C-H⋯F 氢键以及 C-H⋯π 和 Y-X⋯π（Y = B、C；X = F、O）相互作用，在该不对称单元内部以及相邻二聚单元之间形成了固态稳定性，从而产生了双周期薄片和三维扩展网络。

Crystal structure of tricarbonyl[η4-6-exo-(triphenylphosphino)cyclohepta-2,4-dien-1-one]iron(0) tetrafluoroborate

The crystal structure of tricarbonyl[η⁴-6-exo-(triphenylphosphino)cyclohepta-2,4-dien-1-one]iron(0) tetrafluoroborate is described. The two independent tricarbonyl[η⁴-6-exo-(triphenylphosphino)cyclohepta-2,4-dien-1-one] iron(0) cations and their corresponding anions form dimers, which constitute the asymmetric unit of the structure within the (100) plane.

The molecular structure of tricarbonyl[η⁴-6-exo-(triphenylphosphino)cyclohepta-2,4-dien-1-one]iron(0) tetrafluoroborate dichloromethane hemisolvate, [Fe(C₂₈H₂₂O₄)(CO)₃]BF₄·0.5CH₂Cl₂, as determined by single-crystal X-ray diffraction is reported. The two independent tricarbonyl[η⁴-6-exo-(triphenylphosphino)cyclohepta-2,4-dien-1-one] iron(0) cations and their corresponding anions form dimers, which constitute the asymmetric unit of the structure parallel to the (100) plane. Solid-state stability within that asymmetric unit as well as between neighboring dimeric units is afforded by C—H⋯O and C—H⋯F hydrogen bonds and C—H⋯π and Y—X⋯π (Y = B, C; X = F, O) interactions, which yield diperiodic sheets and a three-dimensional extended network.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
