The reactions of Cu(ClO4)2·6H2O and L′H in a variety of solvents have provided access to 12 solvatomorphs of the general formula [Cu(ClO4)2(LH)4]·x(solvent); the effect of the solvents on the packing of the complexes is critically discussed.

Reaction of 4-aminopyridine with silver(I) perchlorate leads to a one-dimensional coordination polymer, {[Ag(C5H6N2)]ClO4}n, in which the aminopyridine binds through both N atoms. The perchlorate anion is hydrogen bonded to the amino H atoms and interacts weakly with the silver(I) atoms (Ag—O > 2.70 Å), both located on inversion centres, and some aromatic H atoms (O—H > 2.55 ÅA), thereby extending the dimensionality of the assembly. This is the first silver complex in which this ligand acts in a bridging mode.

The title compound, {[Cu(NO3)(C2H4N2)(C10H8N2S2)(H2O)]NO3·H2O}n, is composed of a one-dimensional linear coordination polymer involving cis-protected copper(II) ions and a 4,4′-dithiodipyridine bridging ligand. The polymeric chains run along the c-axis direction. N—H
O and O—HO hydrogen bonds involving the coordinating amine groups, nitrate ions and water molecules, as well as cocrystallized noncoordinating nitrate ions and water molecules, generate a three-dimensional structure.

The title molecule, C26H16N2, is nonplanar, the dihedral angle between the two acridine ring systems being 84.67 (7)°. In the crystal structure, intermolecular C—HN and C—Hπ hydrogen-bonding interactions link the adjacent molecules into a two-dimensional network parallel to the ab plane.

In the title polymeric compound, [Mn(N3)2(C13H11N3)2]n, each MnII centre is six-coordinated in an octahedral geometry by six N atoms from four 1-(4-pyridylmethyl)-1H-benzimidazole (L) ligands and two azide anions (N3−). Each of the MnII ions lies on an inversion centre. The L ligands and N3− anions bridge adjacent MnII centres, generating a polymeric chain running along the [110] direction. Adjacent polymeric chains are arranged in a two-dimensional network parallel to the (001) plane, linked by C—HN hydrogen bonds.

There are two molecules in the asymmetric unit of the title compound, C20H14Br2N2. In the first, the dihedral angles between the mean plane of the benzimidazole group and those of the 4-bromobenzyl and 4-chlorophenyl groups are 50.72 (17) and 71.29 (16)°, respectively, while the corresponding angles in the second molecule are 42.09 (16) and 89.05 (17)°. The 4-bromobenzyl and 4-bromophenyl groups make an angle of 68.1 (2) and 85.1 (21)° with each other in the two molecules. In the crystal, weak C—HN and C—HBr hydrogen bonds link the molecules along the c-axis direction. BrBr interactions [3.5733 (9)Å] are also observed.

In the title compound, [Ni(C9H4O6)(C12H12N2)(H2O)2]·7H2O, the NiII atom is six-coordinated by two O atoms from a chelating carboxylate group of a 5-carboxybenzene-1,3-dicarboxylate ligand, two O atoms of two water molecules and two N atoms from a 6,6′-dimethyl-2,2′-bipyridine ligand in a distorted octahedral geometry. The compound exhibits a three-dimensional supramolecular structure composed of the complex molecules and lattice water molecules, which are linked together by intermolecular O—HO hydrogen bonds and partly overlapping π–π interactions between the pyridine and benzene rings [centroid–centroid distances = 3.922 (2) and 3.921 (2) Å]. One of the lattice water molecules is disordered over two positions in an occupancy ratio of 0.521 (6):0.479 (6).

The structure of title compound, C8H8ClN2+·Cl−, comprises discrete ions which are interconnected by N—HCl hydrogen bonds, leading to a neutral one-dimensional network in [001]. This hydrogen bonding appears to complement π–π stacking interactions [centroid–centroid distances 3.768 (2) and 3.551 (2) Å] and helps to stabilize the structure further.

In the title coordination polymer, {[CdI2(C13H11N3)]·0.5CH4O}n, each CdII center is four-coordinated by two N-atom donors from two 1-(4-pyridylmethyl)-1H-benzimidazole (L) ligands and two iodide anions, forming a tetrahedral coordination geometry. L ligands bridge adjacent CdII ions, generating two crystallographically independent approximately orthogonal one-dimensional chains. The methanol solvent molecule associates with one of the chains via O—HI interactions.
