Synthesis, structure and optical studies of inorganic–organic hybrid semiconductor, (H3NC6H4CH2NH3) PbI4

• New type of IO hybrid semiconductor has been synthesized and reported.
• Inorganic (PbI4)2− nano-ribbons are surrounded by organic entities.
• Room-temperature optical exciton and charge-transfer features are reported.
• Structural and optical mechanisms are useful in nanoscale electronic devices.

Synthesis, structural and optical studies of inorganic–organic (IO) hybrid, 1,2-benzyldiammoniumtetraiodo plumbate (H3NC6H4CH2NH3) PbI4 are presented. The titled compound crystallizes into triclinic system of P-1(2) space group with mutually surrounded inorganic (PbI4)2− organic (C7H12N2) entities. These one-dimensional IO hybrids are thermally stable up to 300 °C and show room-temperature exciton along with charge-transfer photoluminescence features. Structural and optical mechanisms are discussed for future applications in nanoscaled optoelectronic devices.
