| 摘 要： | Crystals of the title compound were prepared, whose structure has been determined by X-ray diffraction as a biscrown complex. The crystal is monoclinic with a=22.512 (11), b=22.649(9), c=18.113(8), β=104.84(4)°, V=8926(7)~3, Z=8, space group C2/c. Least square retinement has been performed on 2807 unique observed reflections to a final R of 0.91. It is noted from the structure that K+ is coordinated with ten oxygen atoms, forming an intramolecutar sandwiched complex. The bond distance of K+—O ranges from 2.780 to 3.102 with a mean value of 2.906. Local disorder is observed for SCN-group which distributes on three positions with site occupation factors 0.4, 0.3 and 0.3, respectively.
