The polyborane, carborane, carbocation continuum: architectural patterns
Article Abstract:
Polyboranes, carboranes and carbocations represent the simplest and most abundant class of electron-deficient cluster compounds (those with more valence orbitals than valence electrons). They have the formulas closo-C0-2BnHn+2, nido-C0-4BnHn+4, arachno-C0-6BnHn+6 and hypho-C0-8BnHn+8, where 'n' is the number of boron atoms. The Chop-Styx system of naming these compounds, their electron distributions, the effects of heteroatom substituents and bridge hydrogens on their structures and chemical properties as well as other architectural features are discussed.

Recent advances in phosphinoborane chemistry
Article Abstract:
The phosphinoborane compounds show similar structure and reactivity as the boron-nitrogen analog compounds. The substituent group modifications method is applied to find the condensation and reactivity behavior of unsaturated boron-phosphorous fragments. The coordination chemistry of the compounds also indicates the different electronic structures of the molecules. The preparation and the characterization of the phosphinoborane compounds are described.

Recent advances in the chemistry of carborane complexes incorporating d- and f- block elements
Article Abstract:
A review of the promising researches on metallacarboranes of d-and f- block elements is presented. The current trend of the researches on this field is on finding a practical use of the metallacarboranes and on showing violations of the traditional skeletal elctron-counting rules through the application of solid state struccture determinations. This findings reveal that there are still a lot of useful chemistry in this area that needs to be explored.
