Abstract:
Tetrahedral carbon is a well-accepted structural motif. Theory has paved the way for many rule-breaking planar tetracoordinate carbon structures. Herein, we have explored the possibility of phosphorous supported carbon cluster C(P4)2+ to locate a planar tetracoordinate carbon centre (ptC). Our calculations revealed a penta-atomic planar tetracoordinate carbon (ptC) atom as a local minimum with a significant barrier for interconversion into the lowest energy isomer. The proposed species is kinetically stable and is a probable candidate for experimental detection. The stabilization of the planar structure arises due to delocalization of the p-electrons of the central carbon atom to the surrounding P4 skeleton and significant electrostatic attraction.

The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...
