Abstract

The two novel thioantimonate(III) compounds [Co(C6H18N4)](2)Sb4S8 1 and [Co(C6H18N4)](2)Sb2S5 2 were synthesised under solvothermal conditions by reacting elemental Co, Sb and S in a 95% solution of tris(2-aminoethyl)amine (tren). Compound 1 crystallises in the monoclinic space group P2(1)/c. a = 17.936(4) Angstrom, b = 13.442(3) Angstrom, c = 14.000(3) Angstrom. beta = 101.73(3)degrees, and compound 2 crystallises in the monoclinic space group C2/c, a = 30.157(6) Angstrom, b = 7.720(2) Angstrom, c = 22.875(8) Angstrom, beta = 94.68(3)degrees. The [Sb4S8](4-) anion in compound 1 is composed of two SbS3 and two SbS4 units. The two SbS4 moieties share a common edge and each SbS4 has a common edge with a SbS3 pyramid. This interconnection leads to the formation of three Sb2S2 heterorings. The two remaining terminal S atoms of the anion are bound in a monodentate fashion to the [CO(C6H18N4)](2+) cation. The [Sb2S5](4-) anion in 2 is formed by two corner linked SbS3 units. Two terminal S atoms are bound to the [Co(C6HN4)](2+) cation in a monodentate manner. Compounds I and 2 are the first compounds that contain thioantimonate(iii) anions acting as bridging ligands. Both compounds startto decompose at about 240 degreesC due to the removal of the organic ligands. In the X-ray powder patterns or the decomposition products Sb2S3, CoSbSand CoS could be identified.
