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).
