| Abstract: | Two inorganic-organic hybrid solids, Zn2(phen)(HPO3)2 (1) and Zn(phen)(HPO3) (2), have been synthesized under solvothermal conditions in the presence of 1,10-phenanthroline (phen) ligands. Their structures were determined by single-crystal X-ray diffraction and further characterized by FTIR, elemental analysis, powder X-ray diffraction, thermogravimetric analysis and fluorescent spectra. Compound 1 crystallizes in the triclnic system, space group P-1,  ,  ,  , α=75.609(1)°, β=79.145(2)°, γ=67.157(2)°,  , Z=2. Compound 2 is monoclinic, C2/c,  ,  ,  , β=94.175(4)°,  , Z=8. Both structures consist of 1D chains constructed from strictly alternating ZnO4 and HPO3 polyhedra through sharing vertices. The chains are further decorated by Zn-centered complex architectures, [Zn(phen)]2+ for 1 and [Zn(phen)2]2+ for 2. The 2D and 3D supramolecular arrays for 1 and 2 are stably stacked via strong π-π interactions of the phen groups, respectively. |
