通过对Tamura和Hosokawa的X射线衍射数据应用反向Monte Carlo建模技术，已经详细研究了膨胀汞沿着其液-汽共存曲线的结构（Tamura K和Hosokawa S 1994 J. Phys.：康登斯事项6 A241）。模型表明，随着密度的降低，有一个初始的变化，从一个更紧密的包装，以减少紧密包装的结构。虽然大多数原子对保持相同的近邻距离，约为3.0 A，但少数原子对改变为具有约3.7 A的稍大的近邻距离。在较低的密度下，许多原子具有非常低的配位，这表明它们位于簇的边缘，或簇之间的“路径”上。
The structure of expanded mercury along its liquid-vapour coexistence curve has been studied in detail by applying the reverse Monte Carlo modelling technique to the x-ray diffraction data of Tamura and Hosokawa (Tamura K and Hosokawa S 1994 J. Phys.: Condens. Matter 6 A241). The models suggest that as the density decreases there is an initial change from a more close-packed to a less close-packed structure. Whilst most atom pairs retain the same near-neighbour distance, of about 3.0 A, a few change to having a slightly larger neighbour distance of about 3.7 A. At the lower densities many atoms have a very low coordination, indicating that they are on the edges of clusters, or on `pathways' between clusters.
