This paper gives two empirical correlations of formation Gibbs energies of gaseous clusters Δ<i>G</i><sup>f</sup><sub>n</sub> as function of number of solvent molecules attached to the ion, <i>n</i>, and one correlation connecting the Δ<i>G</i><sup>f</sup><sub>n</sub> for each individual cluster with the total Δ<i>G</i><sup>o</sup><sub>hydr</sub> value. The experimental ratios of Δ<i>G</i><sup>f</sup><sub>2</sub>/Δ<i>G</i><sup>f</sup><sub>1</sub> and Δ<i>G</i><sup>f</sup><sub>3</sub>/Δ<i>G</i><sup>f</sup><sub>1</sub> for both alkali metal and halide ions are on average equal to 0.75 and 0.5, respectively. Δ<i>G</i><sup>f</sup><sub>n</sub> values for <i>n</i> ≥ 4 are correlated with <i>n</i> as Δ<i>G</i><sup>f</sup><sub>n</sub> = [<i>a</i>/(<i>n</i> - 1)] Δ<i>G</i><sup>f</sup><sub>1</sub> + <i>b</i> Δ<i>G</i><sup>f</sup><sub>1</sub>. For all available data on cluster energies and each individual cluster, the Δ<i>G</i><sup>f</sup><sub>n</sub>'s are straight-line functions of Δ<i>G</i><sup>o</sup><sub>hydr</sub>. This well corresponds to another empirical rule stating that the Gibbs energies of transfer of ions between two solvents are often as well straight-line functions of Δ<i>G</i><sup>o</sup><sub>hydr</sub> [J. Rais and T. Okada, <i>J. Phys. Chem. A</i>, <b>2000</b>, <i>104</i>, 7314]. Tentative models of the found behavior are proposed. A full data set of the gaseous cluster energies of formation based on inclusion of new, usually not used entries from the literature is provided.
