Abstract

A mixed-valent copper–antimony sulfide, [H2NCH2CH2NH2]0.5[Cu2SbS3], has been solvothermally synthesized from binary metal sulfides in the presence of ethylenediamine and characterised by single-crystal X-ray diffraction, thermogravimetry, elemental analysis and SQUID magnetometry. The structure of this material consists of chains of fused 5-membered rings of stoichiometry Cu2SbS3, linked into two-dimensional slabs of approximate thickness 5 Å. Neutral ethylenediamine molecules reside between the slabs, to which they are hydrogen bonded. Magnetic susceptibility data yield an effective magnetic moment per formula unit of 0.94(6) μB, consistent with the presence of copper-(I) and -(II) species in the metal sulfide framework.
