Abstract The natural-heterostructure concept realized in delafossites highlights these layered oxides.While metallic, band- or Mott-insulating character may be associated with individual Reclining Loveseat layers, inter-layer coupling still plays a decisive role.We review the correlated electronic structure of PdCoO2, PdCrO2, and AgCrO2, showing that layer-entangled electronic states can deviate from standard classifications of interacting systems.This finding opens up possibilities for materials design in a subtle Mott-critical regime.Manipulated Hidden-Mott physics, correlation-induced semimetallicity, or Dirac/flat-band dispersions in a Mott background Camellia are emerging features.

Together with achievements in the experimental preparation, this inaugurates an exciting research field in the arena of correlated materials.
