The title compound, (C7H10N)3[SbCl5]Cl·H2O, consists of 4-methylanilinium cations, Cl−and [SbCl5]2−anions and water molecules. The five Cl atoms bound to Sb [Sb—Cl = 2.4043 (9)–2.6262 (11) Å] form a square-pyramidal coordination environment. In addition, two [SbCl5]2−anions related by an inversion center are joined by Sb...Cl interactions [Sb...Cl = 3.7273 (14) Å] into an [Sb2Cl10]4−dimer with two bridging Cl atoms. The anions, water molecules and ammonium groups of the cations are linked by N—H...Cl, N—H...O and O—H...Cl hydrogen bonds, forming layers parallel to theacplane. The benzene rings of the 4-methylanilinium cations are packed between these layers.

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.

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.

Distorted Octahedral

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

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 asymmetric unit of the title compound, (C7H10NO)2[SnBr6]·2H2O, contains one cation, one half-dianion and one lattice water molecule. The [SnBr6]2−dianion, located on an inversion center, exhibits a highly distorted octahedral coordination environment, with Sn—Br bond lengths ranging from 2.2426 (9) to 3.0886 (13) Å. In the crystal, O—H...Br, N—H...Br, N—H...O and C—H...Br hydrogen bonds consolidate the packing, which can be described as consisting of alternating anionic (containing dianions and lattice water molecules) and cationic layers parallel toabplane.

In the title compound, {[Cu(C14H8O4)(C4H6N2)2]·2H2O} n , each CuII atom is four-coordinated by two N atoms from two 2-methyl-1H-imidazole (mi) ligands and two O atoms from two biphenyl-2,2′-dicarboxylate (dpdc) anions in a distorted square-planar coordination environment. Each dpdc ligand bridges two neighboring CuII atoms in a bis-monodentate mode, forming a zigzag chain along the b axis. These chains are decorated with mi ligands alternately on the two sides. O—H...O and N—H...O hydrogen bonds involving the water molecules link the chains together, forming a supramolecular structure.

The title compound, [Ni(C6H4NO2)2(C16H38N6)], was prepared through self-assembly of a nickel(II) azamacrocyclic complex with isonicotinic acid. The NiIIatom is located on an inversion center and exhibits a distorted octahedral N4O2coordination environment, with the four secondary N atoms of the azamacrocyclic ligand in the equatorial plane [average Ni—Neq= 2.064 (11) Å] and two O atoms of monodentate isonicotinate anions in axial positions [Ni—Oax= 2.137 (1) Å]. Intramolecular N—H...O hydrogen bonds between one of the secondary amine N atoms of the azamacrocyclic ligand and the non-coordinating carboxylate O atom of the anion stabilize the molecular structure. Intermolecular N—H...N hydrogen bonds, as well as π–π interactions between neighbouring pyridine rings, give rise to the formations of supramolecular ribbons extending parallel to [001].
