Solvothermal Synthesis of [C6H17 N3]Sb10S16: A New Thioantimonate(III) with an
in situ Formed Organic Amine Cation. — Title compound (II) crystallyzes in the
monoclinic space group P21/c with Z = 4 (single crystal XRD). The [Sb10S16]2- anion
consists of nine SbS3 trigonal pyramidal units and one SbS 4 moiety. These primary
building units share common corners and edges yielding Sb3S3 and Sb2S2 rings. Further
condensation leads to strongly undulated two atoms thick layers. Very large Sb31 S31
rings within the layers show a double-ellipsoidal shape. The organic amine cations act
as pillars between successive layers. A remarkable observation is the formation of the
2-piperazine-N-ethylamine cation by cyclization of tris(2-aminoethyl)amine under the
applied solvothermal conditions. — (KIEBACH, R.; NAETHER, C.; BENSCH*, W.;
