Abstract

Two new transition-metal gallophosphates, (H₃DETA)[Mn(H₂O)₂Ga(PO₄) ₂]₃ (1) and (H₃DETA)[Zn₃Ga(PO₄)₄] ·H₂O (2) (DETA = NH₂(CH₂)₂NH(CH₂) ₂NH₂), have been synthesized under mild hydrothermal conditions and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and magnetic susceptibility data. They are the first transitionmetal gallophosphates that adopt chiral frameworks with achiral triamine templates. Both can be prepared in pure chiral forms. The structure of 1 consists of octahedra of MnO₄(H₂O)₂ and tetrahedra of GaO₄ and PO₄ to form a three-dimensional 4-connected polyhedral network in CZP topology. The most interesting feature lies in the fact that the structure is well-sustained with all water ligands removed from the octahedral Mn²⁺ centers. The dehydration -hydration process for the coordination water is reversible. On the basis of TG analysis, material 1 can be thermally stable up to ≈300 °C. Material 2 is built up with tetrahedra of MO₄ (M = Zn and Ga) and PO₄ and crystallizes in the UCSB-7 structure type. It has the highest transition-metal-to-gallium ratio among MGaPOs. Crystal data: 1, orthorhombic, C222₁, a = 10.0390(6) Å, b = 17.389(1) Å, c = 16.7356(9) Å, Z = 4; 2, cubic, 14₁32, a = 17.9192(6) Å, Z = 12.
