Twisted Tin-Chloride Perovskite Single-Crystal Heterostructures.

ABSTRACT: Self-assembly affords simpler synthetic routes to heterostructures compared with manual layer-by-layer stacking, yet controlling interlayer twist angles in a bulk solid remains an outstanding challenge. We report two new single-crystal heterostructures: (Sn₂Cl₂)(CYS)₂SnCl₄ (CYS = ⁺NH₃(CH₂)₂S^-; Sn_CYS) and (Sn₂Cl₂)(SeCYS)₂SnCl₄ (SeCYS = ⁺NH₃(CH₂)₂Se^-; Sn_SeCYS) synthesized in solution, with alternating perovskite and intergrowth layers. Notably, compared to the recently reported lead analog, (Pb₂Cl₂)(CYS)₂PbCl₄ (Pb_CYS), the tin heterostructures feature
