Abstract: | On the Preparation and Crystal Structure of Rb2Sb4S7 Rb2Sb4S7 was prepared by methanolothermal reaction of Rb2CO3 with Sb2S3 at a temperature of 140°C. An X-ray structural analysis demonstrated that the compound contains polythioantimonate(III) anions (Sb4S72?)n, for which the basic element is a ψ-trigonal (SbS4)-bipyramid. Edge bridged SbS4 polyhedra build vierer single chains (Sb4S84?)n, which are linked via two symmetry related S atoms with neighbouring chains so that an (Sb4S72?)n sheet is formed. |
