Abstract
Two new 3D gallophosphate compounds Ga4P5O22H5⋅[C5N2H16] (named JGP-8) and Ga5P6O26H2⋅[C3N2H12]2⋅H3O (named JGP-9) have been synthesized hydrothermally by using organic amines as the template. They are characterized by X-ray powder diffraction (XRD), elemental analysis, inductively coupled plasma (ICP) and TGA analysis and structurally determined by single-crystal X-ray diffraction analysis. JGP-8 crystallizes in the orthorhombic, space group Pbcn (No. 60), with a=25.158(5)Å, b=9.054(2)Å, c=10.166(2)Å, V=2315.6(8)Å3 and Z=4. The 3D anionic framework of JGP-8 is constructed from the inorganic layers and HPO4 tetrahedra, in which the inorganic layers consist of a repetition of novel Ga2P2O10 single four-rings (S4Rs). JGP-9 crystallizes in the triclinic, space group P-1 (No. 2), with a=8.642(2)Å, b=9.510(2)Å, c=10.050(2)Å, α=117.22(3)°, β=93.83(3)°, γ=90.28(3)°, V=732.3(3)Å3 and Z=1. The 3D anionic framework of JGP-9 is built up from the inorganic layers and HPO4 tetrahedra, in which the inorganic layers consist of a repetition of enneameric Ga5(PO4)4O6 structural fragments.
