Organotransition-Metal Metallacarboranes 37. Paramagnetic Iron-Cobalt andDicobalt Triple-Decker Sandwich Complexes

摘要

Multidecker sandwich complexes bridged by planar C2B3 (carborane), C4B (borole),or C3B2 (diborole) rings have been intensively studied both for their intrinsic theoretical interest and as possible building-blocks for polymers or solid-state materials having tailorable electronic and other properties. The electronic structures and chemistry of these complexes are neutral, crystalline, air-stable, soluble in organic solvents exhibit several reversibly accessible redox states. Even more importantly, known synthetic routes have made it possible to prepare entire families of multidecker sandwiches in which the metals and/or substituent groups are systematically varied. This allows much more comprehensive and wide-ranging exploration of the nature of such complexes than would be possible on individual species. jg p.2.
