Abstract [Na4(H2O)14]SnS4 is obtained by the reaction of Na2S·9H2O with SnCl4·5H2O in aqueous solution at 21°C. It crystallizes in the space group Cc with a = 8.621(2) Å, b = 23.543(5) Å, c = 11.358(2) Å, β = 110.58(3)° and V = 2158.2 Å3 with Z = 2. Refinement of 3826 unique reflections from a racemically twinned crystal yielded a final value of R1 = 0.0464 (|F| 〉 4σ) and wR2 = 0.104 and a goodness of fit of 1.125. The structure consists of a Na+/H2O network supporting the tetrahedral SnS4 4− anions. Water molecules or sulfide ions octahedrally coordinate each of the four crystallographically independent Na+ ions. The dominant feature of the structure is the existence of zigzag chains of edgeshared Na octahedra. These chains are tied together into a three-dimensional network by bridging Na(H2O)6 octahedra and individual H2O molecules.
