Synthesis and structure of a non-van-der-Waals two-dimensional coordination polymer with superconductivity.

ABSTRACT: Two-dimensional conjugated coordination polymers exhibit remarkable charge transport properties, with copper-based benzenehexathiol (Cu-BHT) being a rare superconductor. However, the atomic structure of Cu-BHT has remained unresolved, hindering a deeper understanding of the superconductivity in such materials. Here, we show the synthesis of single crystals of Cu₃BHT with high crystallinity, revealing a quasi-two-dimensional kagome structure with non-van der Waals interlayer Cu-S covalent bonds. These crystals exhibit intrinsic metallic behavior, with conductivity reaching 10³S/cm at 300 K and 10⁴S/cm at 2 K. Notably, superconductivity in Cu₃BHT crystals is observed at 0.25 K, attributed to enhanced electron-electron interactions and electron-ph
