Abstract

Hybrid layered double perovskite (HLDP) halides comprise hexacoordinated 1+ and 3+ metals in the octahedral sites within a perovskite layer and organic amine cations between the layers. Progress on such materials has hitherto been limited to compounds containing main group 3+ ions isoelectronic with Pb^II(such as Sb^IIIand Bi^III). Here, we report eight HLDP halides from the A₂M^IM^IIIX₈family, where A = para-phenylenediammonium (PPDA), 1,4-butanediammonium (1,4-BDA), or 1,3-propanediammonium (1,3-PDA); M^I= Cu or Ag; M^III= Ru or Mo; X = Cl or Br. The optical band gaps, which lie in the range 1.55 to 2.05 eV, are tunable according to the layer composition, but are largely independent of the spacer. Magnetic measurements carried out for (PPDA)₂Ag^IRu^IIICl₈and (PPDA)₂Ag^IMo^IIICl₈show no obvious evidence of a magnetic ordering transition. While the t_2g³Mo^IIIcompound displays Curie-Weiss behavior for a spin-only d³ion, the t_2g⁵Ru^IIIcompound displays marked deviations from the Kotani theory.
