Abstract
The title multi-component crystal, [Cu(NH3)5]Cl2·CO(NH2)2, was synthesized from a deep eutectic solvent to yield an unusual pentaaminecopper(II) complex. Hydrogen bonding takes place between chloride ions and both the pentaaminecopper ions and urea molecules.
The reaction of copper(II) oxalate and hexamethylenetetramine in a deep eutectic solvent made of urea and choline chloride produced crystals of pentaaminecopper(II) dichloride–urea (1/1), [Cu(NH3)5]Cl2·CO(NH2)2, which was characterized by single-crystal X-ray diffraction. The complex contains discrete pentaaminecopper(II) units in a square-based pyramidal geometry. The overall structure of the multi-component crystal is dictated by hydrogen bonding between urea molecules and amine H atoms with chloride anions.
草酸铜（II）与六亚甲基烯四矿在尿素和氯化胆碱组成的深共晶溶剂中发生反应，生成了五胺铜（II）二氯化尿素（1/1）晶体，即[Cu(NH3)5]Cl2-CO2-CO(NH2)2，并通过单晶 X 射线衍射对其进行了表征。该复合物含有离散的五胺铜（II）单元，呈正方形金字塔几何结构。多组分晶体的整体结构是由脲分子和胺 H 原子与氯阴离子之间的氢键决定的。
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.
