A metal encapsulated boron atom: preparation and structure of [Fe4(CO)12B{AuPPh3}3]
Abstract
The preparation and structural characterisation of the heterometallic cluster [Fe4(CO)12B{AuPPh3}3] are described: the new compound is the first example of a structurally characterised cluster containing a naked boron atom, i.e. a discrete metal boride cluster; the boron atom is within bonding contact of all seven metal atoms and this unique environment is reflected by an exceptional downfield n.m.r. shift for the 11B resonance.
