Another possible planar tetracoordinate carbon saturated hydrocarbon, a computational study

Abstract

Building on earlier computational work by Radom and Rasmussen, the author found a smaller candidate (C17H16) for a hydrocarbon with a planar tetracoordinate carbon atom than the candidate (C23H24) that had been reported by those workers. This molecule is apparently very unstable but nevertheless significant because it may be the smallest neutral hydrocarbon with such a carbon atom and its smaller size makes it easier to study at high computational levels.
