Structural variations in (001)-oriented layered lead halide perovskites, templated by 1,2,4-triazolium
A new hybrid lead(ii) halide perovskite, (TzH)(2)PbCl4, ([TzH(+)] = 1,2,4-triazolium), adopts a (001)-oriented layered perovskite structure, which can be considered as derived from the n = 1 Ruddlesden-Popper (RP) type. Variable temperature single crystal X-ray diffraction reveals a structural phase transition in the region 125 K < T < 173 K between a high temperature, high symmetry polymorph, space group Cmcm, and a low temperature, low symmetry chiral polymorph, space group P2(1)2(1)2(1), which has a tripled unit cell volume. UV-Vis spectra suggest a band gap of 3.30 eV for (TzH)(2)PbCl4. A second polymorph of the bromide analogue, (TzH)(2)PbBr4-II, is also reported, and structural relationships between all three variants are discussed. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 98475-07-1.
