Abstract
The novel zincophosphates UH-6 (sum formula |[Co(diAMHsar)]| [Zn 2(HPO4)3(PO4)] · H 2O) and UH-10 (sum formula |([Co(diAMHsar)])2| [{Zn 2(HPO4)3(PO4)}2] · H2O) were synthesized in hydrothermal syntheses employing the chiral sarcophagine complex [Co(diAMHsar)]5+ as the structure-directing agent. The inorganic part of UH-6 consists of pearl-like chains of alternating [ZnO4] and [PO4] tetrahedra, which are connected to the incorporated cobalt complex via numerous hydrogen bonds. UH-10 was synthesized under similar conditions, but at higher reaction temperatures. In consequence, the crystal structures of UH-6 and UH-10 are closely related, although systematic disorder in UH-10 and the lower symmetry result in a unit cell twice as large as the corresponding unit cell of UH-6. Interestingly, in both zincophosphates only one enantiomer of the cobalt complex is present, despite the fact that a racemic mixture of the complex salt is used for synthesis. Thermogravimetric analysis and powder X-ray diffraction of a thermally treated sample of UH-6 reveals a phase transformation at ca. 300 °C.
