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).

Distorted Tetrahedral Coordination

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 title complex, [Ag(C5H12N2S)(C18H15P)3](CH3COO)·CH3OH, the AgIion is in a distorted tetrahedral coordination geometry formed by three P atoms from three triphenylphosphane ligands and one S atom from anN,N′-diethylthiourea ligand. In the crystal, the acetate anion is connected to the complex moleculeviaa pair of N—H...O hydrogen bonds [graph-set motifR22(8)] and the solvent methanol molecule is connected to the anionviaan O—H...O hydrogen bond. This aggregate is further connected through a weak C—H...O hydrogen bond, forming a chain along [100]. In addition, sixfold phenyl embraces with intermolecular distances of 6.6463 (13)–6.667 (2) Å are arranged in a chain along [001]. The combination of hydrogen bonding and phenyl...phenyl interactions leads to the formation of a two-dimensional network parallel to (010).

The three-dimensional coordination polymer poly[[bis(μ3-2-aminoacetato)di-μ-aqua-μ3-(naphthalene-1,5-disulfonato)-hexasilver(I)] dihydrate], {[Ag6(C10H6O6S2)(C2H4NO2)4(H2O)2]·2H2O}n, based on mixed naphthalene-1,5-disulfonate (L1) and 2-aminoacetate (L2) ligands, contains two AgIcentres (Ag1 and Ag4) in general positions, and another two (Ag2 and Ag3) on inversion centres. Ag1 is five-coordinated by three O atoms from oneL1 anion, oneL2 anion and one water molecule, one N atom from oneL2 anion and one AgIcation in a distorted trigonal–bipyramidal coordination geometry. Ag2 is surrounded by four O atoms from twoL2 anions and two water molecules, and two AgIcations in a slightly octahedral coordination geometry. Ag3 is four-coordinated by two O atoms from twoL2 anions and two AgIcations in a slightly distorted square geometry, while Ag4 is also four-coordinated by two O atoms from oneL1 and oneL2 ligand, one N atom from anotherL2 anion, and one AgIcation, exhibiting a distorted tetrahedral coordination geometry. In the crystal structure, there are two one-dimensional chains nearly perpendicular to one another (interchain angle = 87.0°). The chains are connected by water molecules to give a two-dimensional layer, and the layers are further bridged byL1 anions to generate a novel three-dimensional framework. Moreover, hydrogen-bonding interactions consolidate the network.

In the title dinuclear complex, [Cu2(C14H20ClN4O)ClO]·3H2O, one CuII cation assumes a distorted square-planar coordination geometry and the other a distorted square-pyramidal coordination geometry. Both CuII cations are N,N′,O-chelated by one arm of the 2,6-bis[(2-aminoethyl)iminomethyl]-4-chlorophenolate anion, and one oxide anion bridges the two CuII cations, forming a dinuclear complex. One of the CuII cations is further coordinated by an Cl− anion in the apical direction. In the crystal, lattice water molecules are linked with the complex molecule via O—H...Cl hydrogen bonds while O—H...O hydrogen bonding occurs between lattice water molecules , forming three-dimensional network structure.

Distorted Trigonal Bipyramidal

The asymmetric unit of the title compound, [Li4(C5H3N2O2)4(H2O)4], contains two symmetry-independent LiIions, two symmetry-independent ligands and two symmetry-independent coordinated water molecules. They form a dinuclear unit in which the two LiIions are bridged by two carboxylate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetrameric molecule. One of the LiIions shows a distorted tetrahedral coordination geometry, the other a distorted trigonal–bipyramidal environment. The tetramers are held together by hydrogen bonds in which coordinated water molecules act as donors, and the carboxylate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.

Each metal ion exhibits a distorted tetrahedral coordination geometry consisting of two pyridyl and two benzimidazole N atoms from four distinct ligands. Two metal ions are linked by two bep ligands to form a centrosymmetric 18-memberedM2(bep)2metallacycle, while adjacentM2(bep)2metallacycles are further interlinked by another two bep ligands resulting in a ladder-like array. In the extended structure, four adjacent ladder-like arrays are connected together through C—H...F, O—H...O and C—H...O hydrogen bonds between bep ligands, solvent molecules and counter-anions into a three-dimensional supramolecular structure.
