| Abstract: | Two homogeneous compounds, {(4-CH3-Bz-4-Ph-Py)PbI3]}n (1) (4-CH3-Bz-4-Ph-Py=4-methylbenzyl-4-phenylpyridinium) and {(4-CF3-Bz-4-Ph-Py)PbI3]}n (2) (4-CF3-Bz-4-Ph-Py=4-trifluoromethylbenzyl-4-phenylpyri-dinium), have been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. Compound 1 crystallizes in orthorhombic, space group P21212, and compounds 1 and 2 are isostructural. Structure analyses reveal that iodoplumbate ion exhibits octahedron topology in compounds 1 and 2, and all these octahedron topologies form 1D polymeric chain through edge-sharing connecting modes. The organic cation fill in the gap formed by inorganic iodoplumbate polymeric chain. |
