Synthesis and Structure of a Chiral Copper(II) Sulfate (C3N2H4)3CuSO4 from Achiral Materials

A novel chiral compound (C3N2H4)3CuSO4 (1) was synthesized at room temperature by using achiral organic amine imidazole as the structure-directing agent, crystallizing in the chiral space group P212121. Single-crystal structural analysis reveals that compound 1 consists of alternating CuO2N3 and SO4 units exhibiting a neutral one-dimensional helical chain.
