Synthesis and crystal structure of sodium (ethane-1,2-di-yl)bis-[(3-meth-oxy-prop-yl)phosphinodi-thiol-ate] octa-hydrate

The title compound, catena-poly[[tri-aqua-sodium]-di-μ-aqua-[tri-aqua-sodium]-μ-(ethane-1,2-di-yl)bis-[(3-meth-oxy-prop-yl)phosphinodi-thiol-ato]], [Na₂(C₁₀H₂₂O₂P₂S₄)(H₂O)₈] _n , crystallizes in the triclinic space group P1. The dianionic [CH₃O(CH₂)₃P(=S)(S-)CH₂CH₂P(=S)(S-)(CH₂)₃OCH₃]^2- ligand fragments are joined by a dicationic [Na₂(H₂O)₈]²⁺ cluster that includes the oxygen of the meth-oxy-propyl unit of the ligand to form infinite chains.
