Four oxygen atoms and a double bond , coordinate to the Ag + ion in the complex with the stilbene crown ether 1 . Surprisingly, the Na + ion is also complexed by 1 in a similar geometry. The coordinative bond between a Na + ion and a π bond, which is detected here for the first time, is probably induced and supported by the oligo(ethylenoxy)oxy bridge. M + X − AgNO 3 , NaClO 4 .
