本文旨在使凝聚相中无机化合物的结构与其熔点和沸点之间的关系合理化。据记载，这两点的主要因素是其分子或聚合物的性质。在聚合离子化合物的情况下，所涉及的离子的实际电荷越高，它们的熔点/沸点越高。在共价聚合物的情况下，这两个点的值随着聚合物维度（1D → 2D → 3D聚合物）以及相应共价键的数量和能量而增加。在分子化合物的情况下，这两点取决于分子的重量和形状，氢键的存在，以及电四极矩。
The paper is aimed at rationalizing relationships between the structure of inorganic compounds in condensed phases and their melting and boiling points. It is documented that the main factor governing both points is their molecular or polymeric nature. In case of polymeric ionic compounds, the higher actual charge bearing by the ions involved, the higher their melting/boiling points. In case of covalent polymers, the value of both points increases with polymer dimensionality (1D → 2D → 3D polymers) and with the number and energy of the respective covalent bonds. In case of molecular compounds, both points depend on the weight and shape of molecules, the presence of hydrogen bonds, and electric quadrupole moment.
