Reaction of strontium amide nacnacSrN(SiMe3)(2)(thf) (nacnac=CH(CMe2,6-iPr(2)C(6)H(3)N)(2)) with PhC CH in THF yields the dimeric alkynyl complex [nacnacSr(thf)(mu-C CPh)](2) which shows an interesting coordination geometry around the metal center. The compound retains the THF molecules, unlike its lighter congener, even in hydrocarbon solvents.journal_article10.1002/asia.20090017819618420000269831700009
