In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni2+cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni2+cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni2+cation has an octahedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N—H...Br, O—H...Br and O—H...O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.

In the title compound, (C9H8N)4[Te2V8O28]·8H2O, the complete heteropolyanion is generated by a crystallographic inversion centre. One of the two quniolinium ions forms an N—H...Op(p = polyoxidometallate) hydrogen bond and the other an N—H...Ow(w = water) hydrogen bond. The water molecules further link the components by O—H...Opand O—H...Owhydrogen bonds. A number of C—H...O interactions and aromatic π–π stacking interactions [shortest centroid–centroid separation = 3.541 (7) Å] are also observed. Together, these generate a three-dimensional network.

Trigonal Prismatic

In the title compound, [Tb(C2H3O2)2(C11H10N4)(H2O)2]NO3·H2O, the Tb3+ ion is nine-coordinated in a distorted tricapped trigonal-prismatic geometry by the three N atoms of the tridentate 1-(pyridin-2-ylmethylidene)-2-(pyridin-2-yl)hydrazine ligand, four carboxylate O atoms of two chelating acetate groups and two O atoms of the coordinating water molecules. The organic hydrazine ligand is disordered over two orientations with a refined occupancy ratio of 0.52 (3):0.48 (3). All bond lengths in the coordination environment of the Tb3+ ion are slightly larger than those observed in the isostructural Y3+ and Er3+ complexes. In the crystal, the complex cations are linked by pairs of O—H...O hydrogen bonds into dimers. These dimers, nitrate anions and non-coordinating water molecules are joined by O—H...O and N—H...O hydrogen bonds into a three-dimensional structure.

In the structure of the title compound, {[Cu2(C10H2O8)(H2O)6]·4H2O}n, the benzene-1,2,4,5-tetracarboxylate ligand, (btec)4−, is located on a crystallographic inversion centre in a μ4-coordination mode. The coordination environment of each pentacoordinated CuIIcentre is square pyramidal (SBP), formed by three water molecules and two carboxylate O atoms from two different (btec)4−ligands. The completely deprotonated (btec)4−ligand coordinates in a monodentate mode to four CuIIatoms. The alternation of (btec)4−ligands and SBP CuIIcentres leads to the formation of a planar two-dimensional covalent network of parallelograms, parallel to theabplane. Hydrogen bonds between a basal water molecule and an apical one from an adjacent [Cu(btec)0.5(H2O)3] unit exist in the intralayer space. Hydrogen bonds are also present between the two-dimensional network and the water molecules filling the channels in the structure.

The 1,10-phenanthroline-chelated CoII atom in the polymeric title compound, {[Co(C7H4O6S)(C12H8N2)(H2O)2]·1.5H2O} n , is connected to the sulfonate O atom of one 4-hydroxy-3-sulfonatobenzoate dianion and to the carboxylate O atom of another dianion. It is also coordinated by two water molecules in a trans-CoN2O4 octahedral environment. The dianion links adjacent metal atoms into a chain running along [110]. The chains are linked by O—H...O hydrogen bonds into a three-dimensional network.

In the binuclear title compound, [Cu2(C8H4O4)Cl(C10H8N2)2(H2O)3]NO3·H2O, the two crystallographically independent CuII ions have similar coordination environments. One of the CuII ions has a square-pyramidal arrangement, which is defined by a water molecule occupying the apical position, with the equatorial ligators consisting of two N atoms from a 2,2′-bipyridine molecule, one carboxylate O atom from a terephthalate ligand and one O atom from a water molecule. The other CuII ion has a similar coordination environment, except that the apical position is occupied by a chloride ligand instead of a water molecule. An O—H...O and O—H...Cl hydrogen-bonded three-dimensional network is formed between the components.
