Crystal structure of [Eu(CyMe4-BTBP)2κ2O,O′-(NO3)](NO3)2·n-C8H17OH and its structure in 1-octanol solution

Abstract

The structure of the [Eu(CyMe₄-BTBP)₂(NO₃)_n]⁽³⁻ⁿ⁾⁺ complex in 1-octanol solution and solid state has been determined by EXAFS and X-ray crystallography. The crystal structure shows that 1-octanol binds only to the europium(III)-coordinated BTBP molecules through weak van der Waals forces, making it the first indication of the role of the extraction solvent.
