  名称：

  Syntheses and crystal structures of mononuclear [2.2]paracyclophane complexes of rhodium and iridium supported by the pentamethylcyclopentadienyl ligand [M(η6-pcp)(η5-C5Me5)](BF4)2 (M=Rh and Ir)

  摘要：

  Mononuclear [2.2]paracyclophane complexes of Rh and Ir, [M(eta(6)-pcp)(eta(5)-C5Me5)](BF4)(2) (M = Rh (1) and Ir (2); pcp = [2.2]paracyclophane) were crystallized and their structures were first characterized crystallographically. On both pep complexes the metal atom is bonded to the benzene ring on one side of the pep ligand in the eta(6)-coordination mode. The metal atom is also supported by the eta(5)-C5Me5 ligand to afford a triple-decker sandwich structure. In Rh pep complex I the average Rh-C(pep) and Rh-C(C5Me5) distances are 2.284(2) and 2.161(2) Angstrom, respectively. The average C(pcp) = C(pcp) distance of 1.407(4) Angstrom with the Rh atom is longer than that (1.388(4) Angstrom) without a Rh atom. Similarly, the average Ir-C(pcp) and Ir-C(C5Me5) distances in Ir pcp complex 2 are 2.275(3) and 2.174(3) Angstrom, respectively. The average C(pcp) = C(pcp) distance of 1.410(4) Angstrom with the Ir atom is longer than that (1.388(4) Angstrom) without an Ir atom. It is interesting that the average interannular distances of 2.97 Angstrom for 1 and 2 between two decks of the pep ligand are shorter than that (3.09 Angstrom) of the metal-free pep ligand, indicative of the decrease of the repulsive pi-interaction between benzene rings. The Rh pep complex gave the well-resolved H-1 NMR signals of [Rh(eta(6)-pcp)(n(5)-C5Me5)](2+), whereas the Ir pep complex exhibited two kinds of H-1 NMR signals which were assigned as [Ir(eta(6)-pcp)(eta(5)-C5Me5)](2+) and [Ir-2(eta(6)-pcp)(eta(5)-C5Me5)(2)](4+) in (CD3)(2)CO at 23 degreesC.
