Hexacoordinated Carbon and Nitrogen Atoms in Extended Organoboron Cage Structures

摘要

The focus of the search for new nonclassical organic and organometallic compounds is currently shifting to compounds containing several centers with hypercoor-dinated main-group elements. This is due to the fact that such systems, composed, as a rule, of building blocks of nonclassical molecules, can form one-, two-, or three-dimensional extended (crystal) structures with novel physicochemical properties. As building blocks, we previously suggested nonclassical organoboron structures 1-4 with a planar four-coordinate carbon atom, from which new structures of the type of 5-10 and others can be formed.
