Bis[(E)-N-(pyridin-3-yl-methyl-idene)hydroxyl-amine-?N(1)]silver(I) perchlorate.

ABSTRACT: Each of the ions in the title salt, [Ag(C(6)H(6)N(2)O)(2)]ClO(4), is completed by the application of crystallographic twofold symmetry. The Ag(I) atom is coordinated by two pyridine N atoms in an almost linear fashion [N-Ag-N = 170.0?(2)°], with the T-shaped coordination geometry being completed by a weakly associated perchlorate-O atom. Supra-molecular zigzag chains along [100] mediated by O-H?N hydrogen bonds [as parts of R(2) (2)(6) loops] feature in the crystal packing. The perchlorate O atoms are disordered over two sets of sites in a statistical ratio.

Project description:In the title salt co-crystal, [Ag(C(6)H(5)N(2)O)(C(6)H(6)N(2)O)]ClO(4)·[Ag(C(6)H(6)N(2)O)(2)], the asymmetric unit comprises a [Ag(LH)(2)](+) cation, a perchlorate anion and a neutral (LH)AgL mol-ecule, where LH is pyridine-2-carboxaldoxime. Both silver-containing species feature N,N'-chelating LH and L ligands, which define an N(4) donor set that is highly distorted [dihedral angles between AgC(2)N(2) chelate rings = 45.7?(3) and 44.3?(2)°, respectively] owing, in part, to the close approach of a neighbouring Ag atom, leading to an argentophilic inter-action [Ag?Ag = 3.1868?(11)?Å]. The mol-ecular conformations are stabilized by intra-molecular O-H?O hydrogen bonds. In the crystal, O-H?O inter-actions lead to supra-molecular chains along [010]. Chains aggregate into layers in the ab plane, defining channels along [100] in which reside the perchlorate anions; the latter are disordered over two overlapped orientations in a 50:50 ratio.

Project description:The title coordination polymer, {[Ag2(C6H5N2O)(C6H6N2O)2]NO3} n , features a deprotonated N-(pyridin-4-yl-methyl-idene)hy-droxy-laminate anion and two neutral N-(pyridin-4-yl-methyl-idene)hydroxyl-amine mol-ecules in the asymmetric unit. The anion connects three Ag(I) atoms through its O and two N-donor atoms. One neutral ligand functions in a monodentate mode; the other functions in a bridging mode, binding though its two N atoms. The coordination geometry of the two independent metal atoms is T-shaped; the manner of bridging gives rise to a layer motif parallel to (100). In the crystal, the nitrate ion is disordered over two positions in a 1:1 ratio, and is sandwiched between adjacent layers. O-H?O hydrogen bonding is present between nitrate ions and layers, and also between adjacent layers.

Bis[(2-methyl-benz-yl)bis-(pyridin-2-ylmethyl-κN)amine-κN]manganese(II) bis-(perchlorate).

Project description:In the title complex, [Mn(C20H21N3)2](ClO4)2, two tridentate (2-methyl-benz-yl)bis-(pyridin-2-ylmeth-yl)amine (L) ligands form the Mn(II) complex [MnL 2](ClO4)2. The Mn(II) ion lies on a twofold axis and the complex cation is significantly distorted from regular octa-hedral geometry. The packing is stabilized by weak C-H⋯O inter-actions between the cations and anions, which link them into a zigzag ribbon along [101]. The perchlorate anion is disordered and was constrained to be tetra-hedral with two orientations having occupancies of 0.768 (4) and 0.232 (4). The 2-methylbenzyl moiety is also disordered over two sets of sites, with occupancies of 0.508 (15) and 0.492 (15).

In the crystal, the nitrate anions link to the dinuclear compound mol-ecules via O-H?O hydrogen bonds, generating a chain running along the a-axis direction.

Project description:The title mononuclear zinc(II) complex, [Zn(C(10)H(15)N(3))(2)](ClO(4))(2), was obtained by the reaction of 2-acetyl-pyridine, N-methyl-ethane-1,2-diamine and zinc perchlorate in methanol. The asymmetric unit of the complex contains two independent [Zn(C(10)H(15)N(3))(2)](2+) cations and four perchlorate anions. The Zn(II) atom in each complex cation is six-coordinated by two pyridine N, two imine N and two amine N atoms from two N-methyl-N'-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine Schiff base ligands in a distorted octa-hedral geometry. The pyridine rings in each of the complex cations are approximately perpendicular to each other, making dihedral angles of 88.4?(3) and 87.9?(3)°. The perchlorate anions are linked to the complex cations through N-H?O hydrogen bonds.

Project description:In the centrosymmetric binuclear title complex, [Ag2(NO3)2(C11H8Cl2N4)2]·2CH3CN, the Ag(I) atom is four-coordinated and exhibits a highly distorted tetrahedral coordination sphere defined by three N atoms from two 1-(3,5-di-chloro-pyridin-2-yl)-2-(pyridin-3-yl-methyl-idene)hy-drazine ligands and one O atom from a nitrate anion. Inter-molecular N-H?O hydrogen bonds link the complex mol-ecules, resulting in a two-dimensional supra-molecular structure parallel to (001).

[(6-Methyl-2-pyridylmeth-yl)(2-pyridylmeth-yl)amine][(2-pyridylmeth-yl)amine]copper(II) bis-(perchlorate).

Project description:The title compound, [Cu(C(6)H(8)N(2))(C(13)H(15)N(3))](ClO(4))(2), is a mixed ligand complex with the Cu(II) atom coordinated by (6-methyl-2-pyridylmeth-yl)(2-pyridylmeth-yl)amine, acting as a tridentate ligand, and 2-(2-amino-meth-yl)pyridine, as a bidentate ligand, leading to an N(5) square-pyramidal geometry. The amine H atoms are involved in hydrogen bonding to the perchlorate O atoms and there are extensive but weak inter-molecular C-H⋯O inter-actions in the crystal structure. The perchlorate ions are each disordered over two positions, with site occupancies of 0.601 (8):0.399 (8) and 0.659 (11):0.341 (11).
