The dinuclear barium–zinc complex, μ-chlorido-1:2κ2Cl:Cl-chlorido-2κCl-bis(2-methoxyethanol-1κO)bis(2-methoxyethanol-1κ2O,O′)bis(μ-triphenylacetato-1:2κ2O:O′)bariumzinc, [BaZn(C20H15O2)2Cl2(C3H8O2)4], has been synthesized by the reaction of barium triphenylacetate, anhydrous zinc chloride and 2-methoxyethanol in the presence of toluene. The barium and zinc metal cations in the dinuclear complex are linkedviaone chloride anion and carboxylate O atoms of the triphenylacetate ligands, giving a Ba...Zn separation of 3.9335 (11) Å. The irregular nine-coordinate BaO8Cl coordination centres comprise eight O-atom donors, six of them from 2-methoxyethanol ligands (four from two bidentateO,O′-chelate interactions and two from monodentate interactions), two from bridging triphenylacetate ligands and one from a bridging Cl donor. The distorted tetrahedral coordination sphere of zinc comprises two O-atom donors from the triphenylacetate ligands and two Cl donors (one bridging and one terminal). In the crystal, O—H...Cl, O—H...O and C—H...Cl intermolecular interactions form a layered structure, lying parallel to (001).

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 structure of the title compound, [HgCl2(C12H20N2)], the HgIIatom has a distorted tetrahedral coordination sphere defined by two tertiary amine N-atom donors, as well as two Cl−anions [the dihedral angle between the N—Hg—N and Cl—Hg—Cl planes is 82.80 (9)°]. The five-membered chelate ring adopts an envelope conformation, with puckering parameters ofQ(2) = 0.446 (6) Å and ϕ(2) = 88.8 (6)°, with the two amine CH3substituents on opposite sides of the ring. In the crystal, the molecules are linked by C—H...Cl interactions into a zigzag chain parallel to [101].

The title compound, [Zn2(C21H25N2)2(OH)2], is a binuclear zinc complex formed by two bidentate β-diketiminate (nacnac) ligands and two μ-hydroxide O atoms, bridging two mononuclear units into a centrosymmetric dimeric unit. Each Zn2+cation is coordinated by two N-donor atoms from the nacnac ligand and two O-donor atoms of hydroxide anions to give a distorted tetrahedral coordination environment. The Zn—O bond lengths are 1.9643 (13) and 2.0022 (14) Å, and the two Zn—N bond lengths are 1.9696 (14) and 1.9823 (14) Å. The distance between the two Zn2+cations in the dimer is 2.9420 (4) Å. Although hydroxide groups are present in the complex, no classical hydrogen-bonding interations are observed because of the bulky β-diketiminate ligands.

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).

Single crystals of MnIn2Se4 have been grown by the chemical vapour phase transport technique using AlCl3 as the transporting agent. The structure was refined to R = 0.064, Rw, = 0.059 for 609 reflections. MnIn2Se4 (R 3̄m, hexagonal axes a = 4.051(1), c = 39.464(2) Å, c/a = 9.74, Z = 3) crystallizes with a nearly close-packed layered structure (sequence of the Se layers ABCA|CABC|BCAB) with Moct (= 0.56 Mn + 0.44 In) in octahedral coordination (Moct,–Se = 6 × 2.721(1) A) and Mtet (= 0.78 In + 0.22 Mn) in tetrahedral coordination (Mtet-Se = 1 × 2.527(2) and 3 × 2.593(1) Å). The overall layer sequences is ΑβΒαCyA| Cα AγBβC| BγCβAα B.

Crystals of the title compound, [Li{OOP(O-2,6-iPr2C6H3)2}(CH3OH)3]·CH3OH or [Li(C24H34O4P)(CH3OH)3]·CH3OH, have been formed in the reaction between HOOP(O-2,6-iPr2C6H3)2and LiOH in methanol. The title compound is of interest as it represents the first reported crystal structure of the family of lithium phosphate diesters. The {Li(CH3OH)3[O2P(O-iPr2C6H3)2]} unit displays the Li atom in a slightly distorted tetrahedral coordination environment and exhibits one intramolecular O—H...O hydrogen bond between a coordinating methanol molecule and the terminal non-coordinating O atom of the phosphate group. The unit is connected with two non-coordinating methanol molecules through two intermolecular O—H...O hydrogen bonds, and with a neighbouring unit through two other O—H...O interactions. These intermolecular hydrogen bonds lead to the formation of infinite chains along [100]. There are no significant interactions between the chains.
