ChemInform Abstract

Co(HSeO₃)Cl×3H₂O and Cu(HSeO₃)Cl×2H₂O are obtained from solutions of CoCl₂ or CuCl₂ in aq. H₂SeO₃. Co(HSeO₃)Cl×3H₂O crystallizes in the triclinic space group P equation image (Z = 2) and adopts an unusual one-dimensional structure formed by corner-sharing pyramidal [HSeO₃]^2- and octahedral [CoO₂(H₂O)₄]^2- and [CoO₂(H₂O)₂Cl₂]^4- units. Interchain bonding occurs via hydrogen bonds or van der Waals interactions. Cu(HSeO₃)Cl×2H₂O crystallizes in the orthorhombic space group Pnma (Z = 8) and contains [HSeO₃]^2- pyramids and Jahn-Teller distorted [CoCl₂(H₂O)₄] and [CoO₄Cl₂] octahedra which share vertices via Cu—O—Se and Cu—Cl—Cu bonds.
