 Title    (CH3NH3)2Sb2S4, a New Thioantimonate(III) with Building Groups Stabilized by Hydrogen Bonds  
 Abstract    (CH3NH3)2Sb2S4 has been isolated from the reaction of antimony with sulfur in the presence of manganese in an ethanolic solution of methylamine under solvothermal conditions. Two pyramidal SbS? units are linked via common S-S edges to give dimeric Sb2S42-anions, which are joined via secondary Sb --S contacts of 3.074(2) and 2.975(2) A forming infinite 1 [SbS2]-^n chains consisting of edge-linked xp-SbS4 trigonal bipyramids. The cis configuration o? the Sb2S42-anions in the title compound is observed for the first time. A specific hydrogen-bonding pattern between the amino-hydrogen and the sulfur atoms stabilizes this configuration and gives rise to anionic layers separated by the methyl groups.
