✦ Synopsis

After two centuries of organic chemistry and the characterization of over 14 million carbon compounds with conventional bonding, our recent computational predictions of molecules with planar hexacoordinate [1] and pentacoordinate carbon atoms [2] has demonstrated that the bonding capabilities of this central element have not been exhausted. We now show computationally [3] that the coordination of carbon can be raised to seven (or six) by the perpendicular extension of two planar hexacoordinate (or pentacoordinate) carbon atoms to form wheel-shaped (W) molecules (e.g. 1 W and 2 W, respectively).
