There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Isocyanide Analogues of the Unsaturated Metal Carbonyls
Inorganic Chemistry Seminar Series
Recent results concerning the construction and reactivity of low-coordinate metal complexes utilizing sterically encumbering m-terphenyl isocyanide ligands are presented. Due to the isolobal relationship between isocyanides and carbon monoxide, these complexes serve as mimics of the unsaturated metal carbonyls. Notably, the latter have traditionally been studied in either the gas phase or by matrix-isolation techniques. Specifically addressed will be synthetic studies which have delivered two- and three-coordinate zero-valent Group 10 complexes that mimic the unsaturated binary carbonyls [Ni(CO)2], [Pd(CO)2] and [Ni(CO)3]. Reactivity studies of these species are also presented. Highlights include an unprecedented one-electron reduction of the N=O bond in nitrosoarenes by a Pd bis-isocyanide complex. In addition, the chemistry of a homoleptic tetra-socyanide of cobalt will be discussed. Remarkably, this species is isolable in three different states of charge and thus formally mimics the tetracarbonyl series, [Co(CO)4]-1, Co(CO)4,⨠[Co(CO)4]+. Detailed structural, spectroscopic, computational and reactivity studies are presented for the full series. Also presented are synthetic and reactivity studies of a three-coordinate isocyanometalate of cobalt.
