Crystal Structure of Cu2Cl4(CH3CN)2, Cu3Cl6(CH3CN)2, and Cu5Cl10(C3H7OH)2

摘要

The crystal structures of three red complexes of copper (II) chloride with the molecular formulas Cu2Cl4(CH3CN)2, Cu3Cl6(CH3CN)2, and Cu5Cl10(C3H7OH)2have been determined. Each compound contains discrete molecules in which the copper atoms and their ligands lie essentially in a plane. Within each molecule, adjacent copper atoms are bridged by two chlorine atoms equidistant from the copper atoms. Each copper atom forms four bonds, with Cusngbnd;Clsime;2.3 Aring; while Cusngbnd;O or Cusngbnd;N bonds are just less than 2.0 Aring;. Bond angles are approximately 90deg;. In all cases the organic molecules are bonded to copper atoms in positions which aretransfor the entire molecule. Molecules are bridged together by longer Cusngbnd;Cl bonds which vary from 2.6 to 3.2 Aring;.
