PHYSICS Correction for “Stable three-dimensional metallic carbon with interlocking hexagons,” by Shunhong Zhang, Qian Wang, Xiaoshuang Chen, and Puru Jena, which appeared in issue 47, November 19, 2013, of Proc Natl Acad Sci USA (110:18809–18813; first published November 4, 2013; 10.1073/pnas.1311028110).
The authors note: “Our paper unfortunately missed reference to an earlier suggestion of the T6 structure (43). This work entitled ‘A hypothetical dense 3,4-connected carbon net and related B2C and CN2 nets built from 1,4-cyclohexadienoid units’ by M. J. Bucknum and R. Hoffmann was published in J Am Chem Soc 116:11456–11464 (1994), where the electronic structure of a hypothetical 3,4-connected tetragonal allotrope of carbon is discussed. The results in this article are consistent with what we find. The same group had also suggested a metallic carbon structure (44) that was published in J Am Chem Soc 105:4831–4832 (1983), which we also missed to cite. We thank Prof. Hoffmann for bringing these papers to our attention.”
