Paramagnetic compds. with at least partially boron-centered electron spin can be constructed using either the prototypically electron-accepting boron atoms bridged by planar p-conjugated org. systems, or by taking advantage of the three-dimensional delocalized bonding in oligonuclear borane, haloborane, or carborane clusters. The concept of mixed valency can thus be transferred from org. and transition-metal chem. to main-group-element mols., and d. functional theory is capable of reproducing the variable spin distribution.
