Crystal and Molecular Structure of {l,2-Bis[2-(o-hydroxyphenoxy)ethoxy]ethane}-bis(isothiocyanato) calcium

摘要

The crystal and molecular structure of {l,2-bis[2-(o-hydroxyphenoxy)ethoxy]ethane}bis(iso-thiocyanato)calcium was studied by single crystal X-ray diffraction.The compound is a host-guest complex.In the molecule of this complex,the podand is "wrapped" around the Ca~(2+) cation (CN 8),which is coordinated with all the six oxygen atoms of the podand and with two nitrogen atoms of two SCN~- ligands.The geometric parameters and crystal packing of the complex were determined.The molecules in the crystal are linked by O-H...S hydrogen bonds to form three-dimensional layers.
