Abstract:
Treatment of p-tert-butylcalix[6]areneH6 (H6L) with [Mo(OBut)2{[2,2′-(N)-C6H4]2(CH2CH2)}] in refluxing toluene affords, after work-up, the complex [Mo(2-NC6H4CH2CH2C6H4NHC(Me)NH-2/)LH2]·4MeCN (1), which contains an 11-membered metallocyclic ring as characterised by Synchrotron X-radiation.
