In the title compound, (C7H11N2)3[Fe(NCS)6]·H2O, the FeIII cation is coordinated by six terminal N-bonded thiocyanate anions into a discrete threefold negatively charged complex. Charge balance is achieved by three protonated 4-(dimethylamino)pyridine cations. The asymmetric unit consists of one FeIII cation, six thiocyanate anions, three 4-(dimethylamino)pyridinium cations and one water molecule, all of them located in general positions.

In the title compound, (C10H10N2S)2[NiCl4]Cl2, the Ni2+ cation is tetrahedrally coordinated by four chloride anions. Two 4,4′-sulfanediyldipyridinium cations and two non-coordinating chloride anions are connected via N—HCl hydrogen-bonding interactions into 20-membered rings, in the middle of which are situated the [NiCl4]2− complex anions. These rings are stacked in the b-axis direction. The Ni2+ cation is located on a twofold rotation axis, whereas the chloride anions and the 4,4′-sulfanediyldipyridinium cations occupy general positions.
