Since it isn't molecular you can scale it by any number. Oftentimes it seems that decimals will be used when the ratio is not fixed. I'm guessing that at different temperatures some of the atoms will move around, while bond distances will change and thus overall the volume stays consistent.
> Not with this stuff, which the team observed across that huge temperature spectrum demonstrating "only minute changes to the bonds, position of oxygen atoms and rotations of the atom arrangements." The team says the exact mechanism behind this extreme thermal stability isn't totally clear, but that perhaps bond lengths, angles and oxygen atom positions are changing in concert with one another to preserve the overall volume.
