Structural diversity in hybrid lead halides templated by 4-methylimidazolium
Abstract
We present several new hybrid organic-inorganic lead(II) bromide materials with interesting polyhedral connectivity templated by [4-MeImH] ([4-MeImH] = 4-methylimidazolium). These include two new examples of a 1D structure-type consisting of edge-sharing chains ([4-MeImH]PbBr3 and [4-MeImH]0.6[ImH]0.4PbBr3, [ImH] = imidazolium); the first example of a 2D layered material containing 7-coordinate Pb, and featuring edge- and face-sharing polyhedra ([4-MeImH]Pb2Br5) and two examples of materials consisting of corner- and face-sharing octahedra; [ImH]PbBr3, which has a 4H-perovskite structure and [4-MeImH]4[ImH]5Pb6Br21, which has a structural resemblance to the 4H-perovskite, but incorporates terminal Br ligands leading to a complex layered structure.
