【 摘 要 】

Reaction of [(bpy)Pd](PF₆)₂ (bpy = 2,2`-bipyridine) with racemic bis(isonicotinoyl)-1,1`-bi-2-naphtholate (L) in acetone, and followed by addition of chloroform and solvent evaporation allows to form amorphous micro-bowl morphology consisting of [(bpy)PdL]₂(PF₆)₄ without any template or additive. In contrast, the reaction and recrystallization in acetone for 1 week produce parallel-piped single crystals consisting of [(bpy)₃Pd₃(_�?3-HPO₄)₂](PF₆)₂. The formations of micro-bowl and parallel-piped single crystal morphologies appear to be primarily associated with the kinetic and thermodynamic control, respectively. The formation of micro-bowls may be attributed to eruption of organic solvents. Cosolvent effects and chemical properties on the formation of micro-bowl morphology have been observed.
