Two new antimony sulphides have been prepared solvothermally and characterised by single-crystal X-ray diffraction. [Co(en)3][Sb 4S7] (1) was prepared at 140 °C from CoS, Sb 2S3 and S in the presence of ethylenediamine, whilst heating a mixture of Sb2S3, Co and S in tris(2-aminoethyl)amine, N(CH2CH2NH2) 3, at 180 °C results in the formation of [C6H 20N4][Sb4S7] (2). Both materials contain [Sb4S7]2- chains formed from linkage of cyclic Sb3S63- units by SbS33- pyramids. In (1), the [Sb4S7]2- chains are linked by secondary Sb-S interactions to form sheets, between which the charge balancing [Co(en)3]2+ cations reside. The structure of (2) involves interconnection of pairs of [Sb4S 7]2- chains through Sb2S2 rings to form isolated [Sb4S7]2- double chains which are interleaved by protonated template molecules. © 2004 Elsevier B.V.
