NaNEt4S4 was obtained from an equimolar solution of Na2S4 and NEt4Cl in ethanol. Its crystal structure was determined by X-ray diffraction with 4175 observed unique reflexions, R = 0.044. Crystal data: a = 713.4(4), b = 1744.5(9), c = 1204.0(5) pm, β = 105.8(3)°, space group P21/n, Ζ = 4. In the structure, chains consisting of Na+ and S42− ions run in the a direction, every Na+ being coordinated by four terminal S atoms of S42− ions (two terminal, one chelating). The chains are separated by the NEt4+ ions.
