Crystal structure and Hirshfeld surface analysis of chiral <i>catena</i>-poly[l-histidinediium [[diiodido-cuprate(I)]-μ-iodido] monohydrate].

ABSTRACT: The title compound, {(C₆H₁₁N₃O₂)[CuI₃]·H₂O} _n or (l-HisH₂)CuI₃·H₂O (1), is a chiral organic-inorganic compound that crystallizes in the monoclinic P2₁ space group. The asymmetric unit of 1 consists of one diprotonated l-histidinium cation {4-[(2S)-2-aza-niumyl-2-carb-oxy-eth-yl]-1H-imidazol-3-ium}, one Cu⁺ cation, three iodide anions, and one co-crystallized water mol-ecule. The Cu⁺ cations is four-coordinated by iodide anions forming a [CuI₄] unit. Structural analysis of the [CuI₄] unit using the Baur, τ₄, and τ₄' indices reveals its slight deviation from ideal te
