A new hybrid inorganic-organic magnetic semiconductor [Ni(bipy){sub 3}Pb{sub 2}I{sub 4.84}Cl{sub 1.16}.DMF]{sub n} (bipy=2,2'-bipyridine) containing novel one-dimensional mixed-halide anion of lead(II) was synthesized by reactions of PbI{sub 2}, NaI, NiCl{sub 2} and bipy in DMF solution, and structurally characterized by single-crystal X-ray diffraction. It crystallizes in the space group C2/c with a=29.260(8) A, b=15.602(4) A, c=23.695(6) A, {beta}=126.815({sup o}), Z=8, V=8660(4) A{sup 3} and consists of a magnetic cation [Ni(bipy){sub 3}]{sup 2+} in addition to one-dimensional mixed-halide anion, which is built up of face-sharing [PbX{sub 6}] octahedra. Of the seven crystallographically independent halide sites in this anion, one and five are occupied by Cl and I, respectively, the remaining one has mixed-iodide and -chloride occupancy. The title yellow compound has an optical bandgap of 2.59 eV, and the variable-temperature magnetic susceptibility measurement indicates paramagnetic behavior. - Graphical abstract: Based upon magnetic metal-organic complex as template, a novel one-dimensional haloplumbate containing mixed-halide anion has been successfully synthesized. Its structural characteristics, optical bandgap, magnetic and thermal properties are reported.
