These two images show crystals grown by 2nd year undergraduates in UCL’s chemistry department, as part of their practical classes this week.
The orange grains in the image above are crystals of ferrocene; the darker granules below are made up of the related substance ferrocenium hexafluorophosphate (also known as ferrocenium FP6)
