Their main types are nido, closo, and arachno, and they are remarkable in that their structures cannot be described with a conventional covalent bond model. The simplest can reduce carboxylic acids to primary alcohols, though it is more commonly done with a sodium salt, as the simplest one is always dimerized. FTP, name these electron-deficient compounds which are the smallest known to have three-center, two-electron bonds.
