Inducing asymmetry in hybrid inorganic\u2013organic metal\u2010halide typically relies on importing chiral A\u2010site cations or exploiting hydrogen bonding to distort the lattice. However, achieving precise spatial control over asymmetrical molecules using stereo\u2010chemical templating strategy remains challenging.
