Abstract

The complex of the podand 1'2-bis[2-(o-hydroxyphenoxy)ethoxy]ethane (L) with ammoniumthiocyanate, [NH4(SCN)L], was prepared, studied by single crystal X-ray diffraction. This is a host-guestcomplex; in its molecule the podand L is “wrapped” around the NH4+ cation, which forms hydrogen bondswith all the six oxygen atoms of the podand and one hydrogen bond with the sulfur atom of the SCN- anion. The geometric parameters (bond lengths, bond angles, torsion angles, etc.) of the molecule of [NH4(SCN)L] and packing of the molecules in the crystal were determined. The molecules are linked into infinite polymeric chains by intermolecular hydrogen bonds O-H···NCS.
