A new silver-antimony sulphide, [C6H20N 4][Ag5Sb3S8], has been synthesised solvothermally in the presence of triethylenetetramine and characterised by single-crystal X-ray diffraction, thermogravimetry and elemental analysis. The compound crystallises in the space group P21/m (a=6.2778(7), b=15.8175(16) and c=12.4617(15)Å and ß=104.561(5)°) and adopts a structure in which honeycomb-like sheets of fused six-membered silver-antimony-sulphide rings are linked through Ag-S bonds to form double layers. The idealised structure can be considered to be derived from that of antifluorite and represents a second structure type for the [Ag 5Sb3S8]2- double layer. © 2005 Elsevier Inc. All rights reserved.
