Abstract: | A thioamide-based pincer Pd complex, [2,6-bis(benzylaminothiocarbonyl-κS)phenyl-κC1]chloropalladium(II), was crystallized from different solvents. The structure of the complex in the solid state depends on hydrogen bonding interactions of cocrystallized solvent molecules with the metal complex in the crystal. The arrangement affects the intensity of the photoluminescence from the crystals. Strong emission was observed from the crystal having a densely packed arrangement of the complex, whereas the solutions and powders of the complex did not exhibit emission. |
