Hi Back in the days when I worked with extremely oxygen and moisture sensitive organometallics (some were pyrophoric given a sniff of oxygen...) I sealed the crystals in capillaries under an argon atmosphere. The huge advantage of this over shipping cryocooled crystals is that they can be packaged safely in a tiny fraction of the volume of a dry shipper, plus you don't have to worry about someone turning your shipper upside-down. We had a custom-built device for mounting the crystals (I have a photo, but because we're currently suffering from a power cut I'm limited to what's available on my portable devices...), but many others just did it in a glove box.
