The title compound is monoclinic, space group P21/n, with a 1.2254(4), b 2.638(1), c 1.0735(3) nm, and b 98.82(2)? Z = 4. The atomic coordinates are given. The structure was solved by direct methods and refined by least-squares to R = 0.053. The IR spectra are described. The Yb3+ ion is not in the cryptand cavity but is connected to it through a H2O bridge by 2 H bonds. The 2 H+ are bound to the 2 N atoms of the cryptand. The Yb3+ is in dodecahedral coordination with the NO3-, NCS-, and H2O. The bond lengths and angles are given.
Key words: CRYSTAL STRUCTURE DETERMINATION, INFRARED SPECTROPHOTOMETRY, YTTERBIUM COMPLEX, ISOTHIOCYANIC ACID, NITRATE P
