Bis[(±)-trans-2-aminocyclohexylammonium] tetrathiomolybdate(VI) and trans-cyclohexane-1,4-diammonium tetrathiomolybdate(VI)

B. R. Srinivasan, C. Näther and W. Bensch

Abstract: The structures of the title complexes, (C₆H₁₅N₂)₂[MoS₄], (I), and (C₆H₁₆N₂)[MoS₄], (II), can be described as consisting of discrete tetrahedral [MoS₄]^2- dianions that are linked to the organic ammonium cations via weak hydrogen-bonding interactions. The asymmetric unit of (I) consists of a single (±)-trans-2-aminocyclohexylammonium cation in a general position and an [MoS₄]^2- anion located on a twofold axis, while in (II), two crystallographically independent trans-cyclohexane-1,4-diammonium cations located on centres of inversion and one [MoS₄]^2- anion in a general position are found. The differing dispositions of the amine functionalities in the organic cations in the title complexes lead to different crystal packing arrangements in (I) and (II).

Formula: (C₆H₁₅N₂)₂[MoS₄] and (C₆H₁₆N₂)[MoS₄]
