Abstract:
(eta 5-Cyclopentadienyl)(kappa 3-hydrotris(pyrazolyl)borate)-cobalt(II) has been synthesised; magnetic and crystallographic data indicate this to be the first example of a high-spin cobalt organometallic complex whilst its pentamethylcyclopentadienyl analogue is found to have a low-spin electronic configuration.
