In the title compound, [Mn(C12H8NO2)2(H2O)4], the Mn2+ ion lies on a twofold rotation axis and has a distorted N2O4 octahedral coordination geometry formed by four water O atoms in the equatorial plane and two apical pyridyl N atoms. A three-dimensional network is formed in the crystal structure by multiple O—H
O hydrogen bonds between the coordinating water molecules and the free carboxylate groups.

In the title compound, [Ni(C9H6N3O3S)2(H2O)2]n, the NiII atom, located on an inversion center, is ligated in an octahedral geometry by two carboxylate O atoms from two 2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}acetate (L) ligands and two O atoms from water molecules in the equatorial plane, and two pyridine N atoms from other two L ligands at the apical sites. Two L ligands bridge pairs of metal atoms in an antiparallel manner, forming centrosymmetric dinuclear quasi-rectangular units which are linked into infinite double-stranded chains parallel to [100]. O—HO hydrogen bonds between the coordinating water molecules and the carboxylate groups of the L ligand as well as interchain SN interactions [2.726 (2)–3.363 (2) Å] lead to the formation of a layer structure parallel to (001).

In the title compound, [Co(NCS)2(C19H17N5O2)2(CH3OH)2], the CoII atom lies on an inversion center and is coordinated by two isothiocyanate N atoms, two O atoms of methanol molecules and two pyridine N atoms in a slightly distorted octahedral environment. Intermolecular O—HO and N—HN hydrogen bonds join the complex molecules into layers parallel to the bc plane.

In the title coordination polymer, {[Gd(C12H8NO2)3(H2O)2]·H2O}n, the GdIII ion is ligated by one bidentate carboxylate group, four monodentate bridging carboxylate O atoms and two water molecules. The resulting GdO8 polyhedron approximates to a square antiprism. The bridging ligands link the metal ions into a [100] chain, with each pair of adjacent metal ions being bridged by two ligands. Inter-chain O—HO and O—HN hydrogen bonds help to establish the packing.
