摘要：
Carbene-metal molecular box: Two imidazolium macrocycles, H 2-1(X)2 and H4-2(PF6)4, act as precursors for the formation of poly(NHC) ligands. The carbene ligands display metal-dependent conformations in forming organometallic complexes. In particular, they are capable of stabilizing boxlike structures such as syn-[Ag2(1)2]2+ and [Ag4(2) 2]4+ when exposed to linearly coordinated silver cations. In contrast, a monomeric species featuring a C-Pd-C angle of about 90° is formed between 1 and PdII. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
