Comment on: Picoscale structural insight into superconductivity of monolayer FeSe/SrTiO3

In a recent paper \"Picoscale structural insight into superconductivity of monolayer FeSe/SrTiO3, Peng et al propose a structure for the Rt13 reconstruction of the SrTiO3 surface. In an comment (eLetter) by L. D. Marks, it is pointed out that this structure both ignores established chemistry, and the existing literature. This deposit has the structure files for the original paper in an xyz format (as provided by Peng et al), and rearranged into a standard CIF format., Original version provided by Peng et al; processed using Wien2k into a standard CIF file, then edited to include bond-valence sums., Standard text files.
