The prototypal hexacoordinate carbon (phC) molecule, CB 6 2- ( D 6 h ), can be annulated by inserting arenes, olefins, or other one or two atom bridging groups into a perimeter B−B bond. Two single-atom units also can bridge opposite CB 6 edges. These strategies allow the design of limitless phC derivatives based on CB 6 as a building block unit. Illustrative examples, shown to be viable computationally, offer possibilities for experimental realization. These phC's involve multicenter deltahedral σ bonding, common for boron but unusual for carbon, in the ring planes, as well as π delocalization.
