The title complex, [Fe2(NCS)4(H2O)6]·3C10H8N6, comprises two FeII atoms octahedrally coordinated and bridged by two aqua O atoms that straddle a crystallographic inversion center, forming a quadrilateral core. The water ligands of the core are involved in hydrogen bonds with the triazole N atoms of the organic molecules, which generates a layer motif in the ab plane. There are π–π stacking interactions between benzene rings of 3.490 (6) Å, and between triazole rings of 3.543 (8) and 3.734 (7) Å in neighboring layers, forming a three-dimensional network.

In the title compound, [Cd(NCS)2(C7H7N5)2(H2O)2], the CdII cation lies on an inversion center and is coordinated by the N atoms of two thiocyanate anions, by N atoms of two 6-(4H-1,2,4-triazol-4-yl)pyridin-2-amine ligands and by the O atoms of two water molecules in a distorted N4O2 octahedral geometry. The dihedral angle between the triazole and pyridine rings is 23.15 (12)°. In the crystal, molecules are linked by N—HN and O—HS hydrogen bonds. Offset π–π stacking between parallel pyridine rings of adjacent molecules is also observed, the centroid–centroid distance being 3.6319 (14) Å.

In the title compound, [Co(NCSe)2(C9H7N7)2(H2O)2], the Co2+ cation is coordinated by two selenocyanate anions, two 2,6-bis(4H-1,2,4-triazol-4-yl)pyridine ligands and two water molecules within a slightly distorted N4O2 octahedron. The asymmetric unit consists of one Co2+ cation, which is located on a center of inversion, as well as one selenocyanate anion, one 2,6-bis(4H-1,2,4-triazol-4-yl)pyridine ligand and one water molecule in general positions. Intermolecular O—HN hydrogen bonds join the complex molecules into layers parallel to the bc plane. The layers are linked by C—HN and C—HSe hydrogen bonds into a three-dimensional supramolecular architecture.

The title compound, C20H17N3O2S2, was synthesized by the reaction of 2-(1,5-diphenyl-1H-pyrazol-3-yloxy)acetic acid and thiazolidine-2-thione. The C-linked benzene ring, N-linked benzene ring and thiazolidine-2-thione ring are twisted 31.33 (2), 62.87 (1) and 82.71 (2)°, respectively, from the plane of the bridging 1H-pyrazole ring. The phenyl rings are oriented at a dihedral angle of 72.16 (2)°.
