Heterobimetallic contacts in statistical co-crystals of homoleptic coordination compounds with ligand-encoded H⋯F bonds: structure, photophysics and mechano-responsive properties

Abstract

In this work, the structural and photophysical characterization of statistical co-crystals based on two homoleptic Pt(II) and Pd(II) complexes as well as their mechano-responsive properties are reported. Ligand-dominated H⋯F bonds, which reinforce metal-metal interactions in the crystalline state, support emission from 3MMLCT states. All co-crystals show a distinct red-shift upon grinding, showcasing their inherent mechano-responsive characteristics stemming from (hetero-)bimetallic contacts.
