The first study of the coordination ability of the [Re12CS14(μ-O)3(OH)6]6− cluster anion was carried out using the cations of alkaline earth metals. Three new compounds displaying supramolecular structures were obtained based on Ca2+, Sr2+ and Ba2+ cations. Compounds K4[M(H2O)7][Re12CS14(μ-O)3(OH)6]·15H2O (M = Ca (1), Sr (2)) demonstrate the structures where disordered Ca2+ or Sr2+ aqua complexes, K+ ions and H2O molecules are stabilized in the channels of anionic sub-lattice formed by cluster anions. Very short hydrogen bonds between the terminal OH− ligands of the cluster anions are observed in these structures. Unlike Ca2+ and Sr2+, the Ba2+ cations are coordinated to the terminal OH-groups as well as to the μ-O2− ligands of the cluster anion forming layered polymeric structure of compound [{Ba(H2O)4}{Ba(H2O)5}2{Re12CS14(μ-O)3(OH)6}]·9H2O (3).
