Molecular structure of a gold β-octakis(trifluoromethyl)-meso-triarylcorrole: an 85° difference in saddling dihedral relative to copper

摘要

Copper corroles exhibit inherent saddling, driven by ligand non-innocence, which may be viewed as a form of multideterminantal character. The saddling is enhanced by sterically hindered peripheral substituents. The sterically hindered complex Cu[(CF₃)₈T(pFP)C] (wherein the ligand is β-octakis(trifluoromethyl)-meso-tris(p-fluorophenyl)corrolato) is thus exceedingly saddled with adjacent pyrrole rings nearly orthogonal to one another. By contrast, Au[(CF₃)₈T(pFP)C] has a nearly planar corrole macrocycle, implying an innocent corrole ligand.View full textDownload full textKeywordsgold, corrole, trifluoromethyl, saddled, multideterminantalRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00268976.2012.695031
