Inorganic–organic hybrid with one-dimensional face-sharing iodoplumbate chain showing novel dielectric anomaly and semiconductor emission

•Inorganic-organic hybrid contains iodoplumbate chain•Hybrid exhibits dielectric anomaly•Hybrid shows semiconductor emission

An inorganic–organic hybrid [tetrabutylammonium][PbI3] crystallizes in tetragonal space group I-42d, which inorganic components form one-dimensional (1D) face-sharing iodoplumbate chain. This hybrid shows a novel dielectric anomaly around 125 °C. The variable-temperature single crystal and powder X-ray diffraction (PXRD) measurements revealed that the dielectric anomaly arises from the disorder–order transformation of tetrabutylammonium. The hybrid emits orange-red luminescence, ascribed to the semiconductor emission of 1D [PbI3]∞ chain.
