Tetrazine-Based Ligand Transformation Driving Metal-Metal Bond and Mixed-Valence Hg^I/Hg^II.

ABSTRACT: Understanding the self-assembly of cluster aggregates remains an important challenge in coordination chemistry. A chelating tetrazine-based ligand was employed to isolate an unprecedented tetranuclear Hg₄ complex exhibiting Hg^I/Hg^II mixed valence, which also contains metal-metal bonds. Single-crystal X-ray diffraction, X-ray photoelectron spectroscopy, solid-state nuclear magnetic resonance, and theoretical approaches (density functional theory) were employed to shed some light on the structure and self-assembly of this discrete molecule.
