- Аннотация: The single-crystal X-ray diffraction analysis of K-2[Co(H2O)(6)](C8H5O4)(4). 4H(2)O has been carried out. The K-2[Co(H2O)(6)](C8H5O4)(4). 4H(2)O single crystals are obtained in attempting to grow the KAP crystals with the maximum possible content of Co2+ impurity cations. The crystals are isostructural to the earlier-studied similar crystals with Ni(II). The structure is formed by double layers of biphthalate anions and the Co2+ and K+ cations in between. The Co2+ cations are coordinated only by water molecules, whereas the coordination of the K+ cations involves both the biphthalate anions and water molecules. A detailed crystal chemical analysis, together with the data on the growth kinetics of KAP crystals in the presence of Co2+ and the mass-spectrometric data obtained earlier for the KAP crystals, leads to the conclusion that the Co2+ impurity cations should be located in the form of the [Co(H2O)(6)](2+) cationic complexes in the interblock layers of the KAP crystals.
