Charge\u2010density plots further illustrate quasi\u20101D electronic anisotropy, showing frontier orbitals confined to the nanoribbons due to covalent Hf\u2500Q bonding. We anticipate heteroanion\u2010driven dimensional reduction can be used to engineer anisotropy in semiconductors and offers new routes to synthetically challenging multianion systems.\n
