Extended Data Fig. 4

a, The parent layered structure (PEA)4CuInCl8 and 1D chain structure (phthalazinium)CuCl2 crystallize with structure directing hydrogen bonds between the organic molecules and the inorganic sublattices highlighted in blue and yellow, respectively. b, The corresponding interactions are highlighted in the templated layered heterostructure (CuCl2)4(HIS)4CuInCl8. Cu, In, Cl, C and N atoms are coloured gold, light-grey, lime-green, grey and blue, respectively. Some H atoms are omitted for clarity.
