Abstract

The crystal, molecular structure of {1'2-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 Ca2+ cation (CN 8), which is coordi- nated 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.
