N2 - 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 PbII(such as SbIIIand BiIII). Here, we report eight HLDP halides from the A2MIMIIIX8family, where A = para-phenylenediammonium (PPDA), 1,4-butanediammonium (1,4-BDA), or 1,3-propanediammonium (1,3-PDA); MI= Cu or Ag; MIII= 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)2AgIRuIIICl8and (PPDA)2AgIMoIIICl8show no obvious evidence of a magnetic ordering transition. While the t2g3MoIIIcompound displays Curie-Weiss behavior for a spin-only d3ion, the t2g5RuIIIcompound displays marked deviations from the Kotani theory.
