Benzo-18-crown-6ÐAcetonitrile (1/2), Crystal Structure

Single crystals of the title complex resulted fortuitously during an attempt to co-crystallise MeN(SO2Me)2 with benzo-18-crown-6 from an MeCN solution at Ð30∞C. The crystal structure has been determined via data collection at Ð100∞C (monoclinic, space group P 21/n, Z= 4).

The nitrile molecules are located with their me- thyl groups above and below the plane of the 18- membered crown ring, the Me hydrogen atoms being rotationally disordered about the MeCN axes; C(methyl) ··· O(crown) distances range from 309.4(3) to 384.9(3) pm.
