Thiolate complexes of iridium. Structures of [Ir2(μ-SC6F5)2(cod)2], [Ir(SC6F5)(H)(SiPh3)(XNC)3] and [Ir3(μ-SC6F5)2(SC6F5)(μ,μ′-XNC)(XNC)4(cod)] (XNC=xylyl isocyanide)
摘要:
The complex [Ir(2)(mu-SC(6)F(5))(2)(cod)(2)] (1) (cod = 1,5-cyclooctadiene), readily prepared in good yield from [Ir(2)(mu-OMe)(2)(cod)(2)], combines with Ph(3)SiH and XNC (XNC = 2,6-dimethylphenylisocyanide, xylyl isocyanide) in benzene to give [Ir(SC(6)F(5))(H)(SiPh(3))-(XNC)(3)] (2). With XNC alone, in CH(2)Cl(2), 1 reacts to give, among other, unidentified products, [Ir(3)(mu-SC(6)F(5))(2)(SC(6)F(5))(mu,mu'-XNC)(XNC)(4)(cod)] (3). The X-ray crystal structures of 1, 2 and 3 are reported. (C) 2008 Elsevier Ltd. All rights reserved.
