- Аннотация: Phenylenediammonium polyiodobismuthate(III), [PDA(BiI4)2•I2] (PDA = phenylenediammonium, [NH3C6H4NH3]2+), represents a new hybrid halometallate synthesized in a form of black well-shaped crystals by a facile reaction in aqueous solution of HI containing dissolved I2. It crystallizes in triclinic space group P-1 with the unit cell parameters a = 7.761(1), b = 9.259(1), c = 9.689(1) Å, α= 95.68(3), β = 103.19(3), γ = 93.56(3)o, and Z = 1. Its crystal structure comprises three levels of organization discriminated by a type of chemical bonding. The first level is provided by covalently bonded [BiI6] octahedra linked into [BiI4]∞– one-dimensional anionic chains; the second level features secondary bonds between the chains and I2 bridging molecules; whereas the third level is specified by the weak hydrogen N–H•••I bonds involving diammonium cation and I•••I intermolecular interactions that additionally link anionic chains. Altogether, these three interaction types ensure the formation of a complex pseudo-three-dimensional crystal structure. According to optical absorption study, [PDA(BiI4)2•I2] is a semiconductor with the band gap of 1.45 eV.
