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