Abstract:
A new iodiplumbate polymer [(ipq)2(pea)(Pb3I 9)·DMF]n 1 (ipq = N-isopentyl)-quinolinium, pea = protonated ethylamine) was synthesized by self-assembly reaction of ipq·I, PbI2 with ethylamine and structurally characterized. 1 crystallizes in the triclinic system, space group P1̄ with a = 1.0731(4), b = 1.2560(4), c = 2.0785(7) nm, α = 96.378(5), β = 91.132(2), γ = 100.303(5)°, V = 2.7369(16) nm3, Z = 2, Dc = 2.770 g/cm3, μ = 14.307 mm-1, F(000) = 2014, R = 0.0588 and wR = 0.1345. 1 features its hybrid structure conceitedly templated by two kinds of organic cations, which exhibits interesting semiconductor property. In 1, the [Pb2I6]2-n infinite chains shape the sketch of the title compound constructed from face-sharing of ideal and distorted PbI6 octahedra. Based on the crystal structure data, quantum chemistry calculation with DFT was used to reveal the electronic structure of 1.
