I am growing crystals of an air/moisture sensitive compound in a glove box. During the sample preparation for single-crystal XRD crystals will be crushed upon removal from the glass container.
Probably, the crystal contains solvent molecule within it. Try to grow crystal from another set of solvent e.g. solvent having high boiling point, high molecular weight and or having interacting (through H-bond, pi-interaction, neutral donating site) site/s. If possible, take the crystal in polybutenes oil with in the glove box and store over liquid nitrogen (outside of the glove box) until the mounting of crystal on the single crystal XRD analyzer.
