Effect of arsenic coordination state on the structure, aromaticity, and optical properties of dithieno[3,2‐b:2’,3’‐d]arsoles

A silylated derivative of 4‐phenyl‐dithieno[3,2‐b:2’,3’‐d]arsole (DTAs) was synthesized, and the effect of coordinating of DTAs compounds to Pd on their structural and optical properties was investigated. Coordination of the As to Pd was found to increase the structural aromaticity of the ring system as measured by the harmonic oscillator measure of heterocyclic electron delocalization (HOMHED), and the pyramidalization of the As atoms was also found to show a good correlation with the HOMHED values. However, coordination had a more subtle impact on the optical properties than seen for phosphorus‐containing analogues as the metal‐ligand interactions were weaker.
