Structural features in some layered hybrid copper chloride perovskites
Abstract
We present three new hybrid copper(II) chloride layered perovskites of generic composition ACuCl<sub>4</sub> or A<sub>2</sub>CuCl<sub>4</sub>, which exhibit three distinct structure types. (m-PdH<sub>2</sub>)CuCl<sub>4</sub> (m-PdH<sub>2</sub><sup>2+</sup> = protonated m-phenylenediamine) adopts a Dion–Jacobson (DJ)-like layered perovskite structure type and exhibits a very large axial thermal contraction effect upon heating, as revealed via variable-temperature synchrotron X-ray powder diffraction (SXRD). This can be attributed to the contraction of an interlayer block, via a slight repositioning of the m-PdH<sub>2</sub><sup>2+</sup> moiety. (3-AbaH)<sub>2</sub>CuCl<sub>4</sub> (3-AbaH<sup>+</sup> = protonated 3-aminobenzoic acid) and (4-AbaH)<sub>2</sub>CuCl<sub>4</sub> (4-AbaH<sup>+</sup> = protonated 4-aminobenzoic acid) possess the same generic formula as Ruddlesden–Popper (RP) layered perovskites, A<sub>2</sub>BX<sub>4</sub>, but adopt different structures. (4-AbaH)<sub>2</sub>CuCl<sub>4</sub> adopts a near-staggered structure type, whereas (3-AbaH)<sub>2</sub>CuCl<sub>4</sub> adopts a near-eclipsed structure type, which resembles the DJ rather than the RP family. (3-AbaH)<sub>2</sub>CuCl<sub>4</sub> also displays static disorder of the [CuCl<sub>4</sub>]<sub>∞</sub> layers. The crystal structures of each are discussed in terms of the differing nature of the templating molecular species, and these are compared to related layered perovskites. Preliminary magnetic measurements are reported, suggesting dominant ferromagnetic interactions.
