The title hydrated complex, [Zn2Cl4(C9H12N4)2]·2H2O, is a discrete dinuclear zinc complex with 1,3-bis(1H-imidazol-1-yl)propane as the bridging ligand. The complex molecule lies about a crystallographic inversion centre. The ZnIIatom exhibits a distorted tetrahedral coordination geometry defined by two imidazole N atoms and two Cl atoms. O—H...Cl hydrogen bonding between the lattice water molecules and the terminal Cl atoms of the molecule lead to a two-dimensional structure extending parallel to (100).

In the crystal structure of the title complex, [Cu(C10H9N3)2](ClO4)2, the CuIIcenter is four-coordinated by the nitrogen donors of the pyridine rings of the ligand, bis(2-pyridyl)amine. The crystal structure reveals that the CuN4coordination sphere has a distorted tetrahedral coordination geometry with a crystallographicC2axis through the CuIIcenter. The perchlorate anions link the complex cations to form a chain structure through C—H...O close contacts and N—H...O hydrogen bonds.

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each AgIion displays a distorted tetrahedral coordination geometry with two P atoms from two bis(diphenylphosphanyl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from theN,N′-phenylthiourea (ptu) ligand. The dppm ligands and the bridging chloride ion force the two Ag atoms into close proximity, with a short Ag...Ag separation of 3.2064 (2) Å. In the crystal, complex molecules are linked by N—H...Cl hydrogen bonds forming a dimer. The dimers are linkedviaweak C— H...Cl hydrogen bonds forming a two-dimensional supramolecular architecture in theyzplane. In addition, an intramolecular N—H...Cl hydrogen bond is observed.

In the title complex [systematic name: bis(2,4-di-tert-butyl-6-{N-[4-(dimethylamino)phenyl]carboximidoyl}phenolato)cobalt(II)], [Co(C23H31N2O)2], the cobalt(II) atom is coordinated by pairs of O and N atoms in a distorted tetrahedral coordination geometry. The dihedral angles formed by the aromatic rings of the same ligand are 51.99 (11) and 36.58 (9)°. The molecular conformation features weak intramolecular C—H...O hydrogen bonds. In the crystal, inversion-related pairs of complex molecules are linked into dimers by weak C—H...π interactions. The methyl C atoms oftert-butyl groups have rotational disorder, with site occupancies of 0.647 (7) and 0.617 (6) for the major components and 0.353 (7) and 0.383 (6) for the minor components. One of the methyl C atoms of the dimethylamino groups is also disordered over two orientations, with an occupancy ratio of 0.75 (4):0.25 (4).

The synthesis and characterisation of zinc(II) complex with 2-amino-5-bromopyridine (C5H5BrN2) ligand have been described. The complex was structurally characterised via X-ray crystallography, in the title compound, (2-amino-5-bromopyridinium) [ZnCl¬3(2-amino-5-bromopyridine)] or which is also called (C5H6BrN2) [ZnCl3(C5H5BrN2)]¬. The Zn(II) atom is four-coordinated by three Cl atoms and one imine N-atom of 2-amino-5-bromopyridine ligand, forming a distorted tetrahedral coordination geometry. The complex was also investigated by elemental analysis, 1H NMR, IR spectroscopy and UV-Visible absorption. The protonation behaviour upon coordination is discussed.

In the mononuclear mixed-ligand title complex, [AgCl(C7H7NS)(C18H15P)2], the AgIion is four coordinated by one S atom of a benzenecarbothioamide ligand, two P atoms of two triphenylphosphane ligands and one chloride ion, displaying a distorted tetrahedral coordination geometry. In the crystal, pairs of N—H...Cl hydrogen bonds form inversion dimers. An intramolecular N—H...Cl hydrogen bond is also observed.

In the title complex, [Ag(NO3)(C2H3N3S)(C18H15P)2]·CH3OH, the AgIion exhibits a distorted tetrahedral coordination geometry formed by two P atoms from two triphenylphosphine ligands, one S atom from a 1H-1,2,4-triazole-5(4H)-thione ligand and one O atom from a nitrate ion. In the crystal, complex and solvent molecules are linked by O—H...O and N—H...O hydrogen bonds forming a chain along theb-axis direction. The chains are linked by weak C—H...O hydrogen bonds forming a two-dimensional supramolecular architecture parallel to (001). In addition, an intramolecular N—H...O hydrogen bond is observed.

The title complex, [ZnCl2(C16H17NO2)2], displays a distorted tetrahedral coordination geometry around the ZnII ion. The Schiff base inner salt, (benzylimino)ethyl-5-methoxyphenol, coordinates in a monodentate manner to the ZnII ion via the deprotonated hydroxy groups. The protonated imino groups form intramolecular hydrogen bonds with the deprotonated hydroxyl groups of the same Schiff base ligand.
