%X The crystal structure of the title compound [K(-NHCH2CH2OCH2CH2OCH2CH2NHCH2CH2OCH2CH2-)(NCS)] has been determined. Potassium(I) is 1.41 &#506; above the plane of the three oxygens of the 4,7,13-trioxa-1,10-diazacyclopentadecane ligand, and is seven-coordinated. Potassium(I) is 2.871(7), 2.798(7) and 2.772(7)&#506; from the three oxygens, and 2.905(8) and 2.945(8)&#506; from the two nitrogens of 4,7,13-trioxa-1,10-diazacyclopentadecane, 2.861(7)&#506; from an oxygen of a second such ligand, and 2.809(8)&#506; from the thiocyanate nitrogen. Crystals are monoclinic, space group P21/n with unit cell parameters a 8.015(4), b 14.755(4), c 13.744(4)&#506;, &#946; 95.37(3)&#176;, and Z 4. The structure was solved by direct methods and refined by a full-matrix least-squares procedure to final R 0.089, Rw 0.099 for 981 reflections with I &#8805; 2.5&#963;(I).
