Single Crystals of Naturally Occurring Gas Hydrates: The Structures of Methane and Mixed Hydrocarbon Hydrates

Samples from the bottom of the sea were used in the exact determination of the crystals structures of naturally occurring hydrocarbon hydrates. The hydrates of methane, ethane, and propane had a cubic structure II with hexakaidecahedral and pentagonal dodecahedral cages occupied by the guest molecul...

Summary:Samples from the bottom of the sea were used in the exact determination of the crystals structures of naturally occurring hydrocarbon hydrates. The hydrates of methane, ethane, and propane had a cubic structure II with hexakaidecahedral and pentagonal dodecahedral cages occupied by the guest molecules (see picture; C blue, H gray, O white).
