摘要：

A new uranium metallacyclocumulene, (C5Me5)(2)U(eta(4)-1,2,3,4-PhC4Ph), was synthesized by both reaction of (C5Me5)(2)UCl2 with 1,4-diphenylbutadiyne in the presence of KC8 and by ligand exchange between (C5Me5)(2)U(eta(2)-Me3SiC2SiMe3) and 1,4-diphenylbutadiyne. Full characterization of (C5Me5)(2)U(eta(4)-1,2,3,4-PhC4Ph) is reported, including the solid-state structure. (C5Me5)(2)U(eta(4)-1,2,3,4-PhC4Ph) displays an unusually detailed UV visible spectrum, which is rare for uranium(IV) metallocene complexes. (C) 2016 Elsevier B.V. All rights reserved.
