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.

Zinc (hydrogen-β -glutamate) chloride hydrate is readily prepared from equimolar quantities of [Zn (β -GluH)2] and ZnCl2 in water. The crystal structure shows a coordination polymer with zinc atoms bridged by the 3-ammonio-glutarate ligand. The tetrahedral coordination sphere of the metal atom is completed by the chloride anion and the water molecule.

[Cu2L(prz)] (prz = 3,5-dimethylpyrazole and L = 1,3-bis(5-bromo-2-hydroxybenzylidene)- propan-2-ol) was synthesized and its crystal structure determined. It crystallizes in the orthorhombic space group Pbca with a = 14.160(9), b = 15.109(4), c = 21.298(5) Å, V = 4557(1) A3, Z = 8 . Two copper(II) ions are in a square-planar coordination. The metal coordination sphere is four-coordinate, with a planar N2O2 donor set. The dihedral angle between the two coordination planes is 12.14(7)°. The copper(II) centers are separated by 3.365(1) Å and antiferromagnetically coupled (J = -214.3 cm-1), which follows from temperature-dependent magnetic susceptibility measurements in the temperature range 4.6 to 310 K. The Cu-O-Cu angle is 125.9(1)° in the super-exchange pathway. The magnetic moment at 310 K is ca. 1.76 B.M. and 0.13 B.M. at 4.6 K.

The complete molecule of the hexametallic title complex, namely, tetrabromidotetra-μ-hydroxido-hexakis[μ-2-methyl-3-(pyrrolidin-1-yl)propan-2-olato]hexazinc(II) acetone disolvate, [Zn6Br4(C9H18NO)4(OH)4]·2C3H6O2, is generated by a crystallographic centre of symmetry. Two of the unique zinc atoms adopt distorted ZnO2NBr tetrahedral coordination geometries and the other adopts a ZnO3N tetrahedral arrangement. Both unique alkoxide ligands are N,O-chelating and both hydroxide ions are μ2 bridging. The crystal structure displays an O—H...O hydrogen bond between a μ2-OH group and an acetone solvent molecule. The Hirshfeld surface has been calculated and is described.

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 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).

Distorted Tetrahedral Coordination

The title complex, [AgBr(C7H7NS)(C18H15P)2], was obtained from the reaction of silver(I) bromide with benzenecarbothioamide (C7H7NS) and triphenylphosphane (C18H15P) in the mixed solvent of acetonitrile and ethanol. The mononuclear complex exhibits a distorted tetrahedral coordination geometry about the metal atom, arising from one S atom of a benzenecarbothioamide ligand, two P atoms of two triphenylphosphane molecules and one bromide ion. An intramolecular N—H...Br hydrogen bond is observed and in the crystal structure, inversion dimers linked by pairs of N—H...Br and C—H...Br hydrogen bonds are observed. In addition, C—H...π interactions occur, leading to [101] chains. Hirshfeld-surface analyses are presented and discussed.
