Retraction of “Metallic Conductivity in a Two-Dimensional Cobalt Dithiolene Metal–Organic Framework”

Abstract

The authors retract this Article (10.1021/jacs.7b05742) following concerns raised about the temperature-dependent resistivity data. The authors recharacterized the samples and determined that the anomalous temperature-dependent maxima reported were not due to metallic conductivity. Instead, it was found that ohmic contact was lost during cooling. This resulted in a significant reduction to the current passing between the electrodes, which could not be detected using the equipment available at the time. The authors note that the density functional theory (DFT) calculations, synthetic studies, synchrotron X-ray powder diffraction, modeling, Brunauer–Emmett–Teller (BET) measurements, scanning electron microscopy and atomic force microscopy, and magnetic susceptibility measurements stand on their own merit. However, due to the misinterpretation of the conductivity data, the findings of the work are incorrect, and thus the paper is being retracted. The original Article was published on July 13, 2017, and retracted on April 7, 2025. This article has not yet been cited by other publications.
