A new chromium-antimony-sulfide, [Cr(C6H18N 4)(SbS3)], has been synthesised under solvothermal conditions from CrCl3 · 6H2O, Sb2S 3 and S in the presence of triethylenetetramine at 433 K and characterised by single-crystal X-ray diffraction, thermogravimetry, elemental analysis and SQUID magnetometry. The structure of [Cr(C6H 18N4)(SbS3)] consists of neutral mononuclear chromium-centred complexes, in which the Cr3+ is chelated by one tetradentate triethylenetetramine molecule and a bidentate SbS33- ligand, yielding distorted octahedral coordination. Intermolecular hydrogen bonds link individual molecules into layers within the ac plane. Within a layer, molecules occur in pairs with each member related by a centre of inversion. The Cr?Cr separation within a pair is approximately 6.5 Å. Magnetic susceptibility data reveal Curie-Weiss behaviour with µeff = 3.819(3) µB and a negligible Weiss constant, indicative of non-interacting Cr3+ ions. © 2003 Elsevier Science Ltd.
