. Expert Experimentalist Rating: “The Single-Crystal Shakedown”
Overview:
X-Ray diffraction is an important and powerful tool for determining the solid state
structure pounds. Modern advances have made data collection and structure solution
almost routine for many small molecules. To use this technique, however, good quality
single crystals are still needed. In this exercise, you will experiment with the art of growing
single crystals.
Techniques Checklist:
• Manipulation of milligram quantities of material ❑
• Syringe use ❑
• Crystallization techniques for growing good quality single crystals ❑
Pre-Lab Discussion:
• Use of different recrystallization techniques: vapor diffusion, solvent layering,
temperature variation
Goal:
Synthesize Cr(acac)3,2 then perform several slow recrystallizations to obtain a single
crystal of satisfactory quality.
Equipment:
