A Molecular "A-Type" Tangled Metallocube.

Tangled cubes feature the topology of typical Platonic cubes, with their "faces" traversed by edges in different ways. This study generates an "A-type" tangled metallocube from the reaction of binuclear gold-NHC complex and H 2 S. The tangled cube topology was validated by multinuclear nuclear magnetic resonance (NMR) spectroscopy, high-resolution electrospray-ionization (HR-ESI) mass spectrometry, and single-crystal X-ray diffraction analysis. This study offers a simple and effective approach to designing and fabricating new, topologically unique molecular structures.
