Computational organic chemist Steven Bachrach discussed the dication, noting that the weak bonds forming the upright edges of the pyramid, shown as dashed lines in the structure he drew, have a Wiberg bond order of about 0.54; it follows that the total bond order for the apical carbon is 5 × 0.54 + 1 = 3.7 < 4, and thus the species is not hypervalent, but it is hypercoordinate.
Steven Bachrach, a computational organic chemist, analyzed the dication's structure to determine its bonding characteristics. He found that the apical carbon atom has a bond order less than 4, indicating it is not hypervalent but rather hypercoordinate.
