The title compound, Li3.5Eu1.5(MoO4)4, was prepared by solid-state reactions. The fundamental building units of the structure are LiO4 polyhedra (site symmetry ), distorted LiO6 polyhedra and MoO4 tetrahedra, which are further interconnected via corner-sharing O atoms. One site is occupied by both Li and Eu atoms in a substituent disordered manner (0.25:0.75), and the Li/Eu atoms are coordinated by eight O atoms in a distorted square-antiprismatic manner.

The asymmetric unit of the title compound, {[MgNa2(C10H4O8)2(H2O)8]·2H2O}n, contains one octahedrally coordinated MgII atom (site symmetry 2/m), one octahedrally coordinated NaI atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetracarboxylate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (–Na–Na–Mg–)n chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by μ4-bridging btec ligands, which form intermolecular O—HO hydrogen bonds to uncoordinated water molecules and the coordinated water molecules of a neighbouring chain. In each btec ligand, there are also intramolecular O—HO hydrogen bonds.

In the title compound, [NiCl(C10H7N3S)2(H2O)]NO3, the NiII ion is coordinated by four N atoms from two chelating 2-(1,3-thiazol-4-yl)-1H-benzimidazole ligands, one Cl atom and one water molecule in a distorted octahedral geometry. In the crystal, O—HO, N—HO and N—HCl hydrogen bonds link the complex cations and nitrate anions into a three-dimensional network. π–π interactions between the thiazole and imidazole rings and between the thiazole and benzene rings are observed [centroid–centroid distances = 3.592 (3) and 3.735 (3) Å].

In the title compound, [CoCl(C10H7N3S)2]Cl·2H2O, the CoII atom is five-coordinated by four N atoms from two chelating 2-(1,3-thiazol-4-yl)-1H-benzimidazole ligands and one Cl atom in a distorted trigonal–bipyramidal geometry. In the crystal, N—HO and O—HCl hydrogen bonds and π–π interactions between the thiazole, imidazole and benzene rings [centroid-to-centroid distances 3.546 (2), 3.683 (2) and 3.714 (2) Å] link the complex cations, chloride anions and uncoordinating water molecules into a three-dimensional network.
