ABSTRACT: In the centrosymmetric dinuclear title Ag(I) compound, [Ag2(C6H6N2O)4](NO3)2, the aromatic amine-coordinated Ag(I) atom is further bridged by two hydroxyl-amine mol-ecules that use aromatic and oxime N atoms for bridging, and it exists in a distorted trigonal-planar geometry. 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.

(Tris{2-[(5-hy-droxy-pyridin-2-yl-κN)methyl-idene-imino-κN]eth-yl}amine)-zinc dinitrate.

Project description:In the complex cation of the title compound, [Zn(C(24)H(27)N(7)O(3))](NO(3))(2), the tripodal tris-{[2-(5-hy-droxy-pyridin-2-yl)methyl-idene-imino]-eth-yl}amine ligand is coordin-ated to the Zn atom through the three pyridine and three imino N atoms. The coordination sphere of the Zn atom is based on an octahedron with a significant distortion towards trigonal prismatic, the twist angle being 45.58 (9)°. The crystal packing is formed by L and D anti-podes arranged in layers disposed parallel to the b axis. Strong O-H⋯O hydrogen bonding exists between the hy-droxy groups of the ligand and the nitrate anion.

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.

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

Project description: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: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.

Diaqua-bis-{2-hy-droxy-5-[(pyridin-2-yl)methyl-idene-amino]-benzoato-κN,N'}zinc(II) dihydrate.

Project description:The complex mol-ecule of the title compound, [Zn(C(13)H(9)N(2)O(3))(2)(H(2)O)(2)]·2H(2)O, has 2 symmetry with the Zn(II) cation located on a twofold rotation axis. The Zn cation is N,N'-chelated by two 5-[(pyridin-2-yl)methyl-idene-amino]-2-hy-droxy-benzoate anions and coordinated by two water mol-ecules in a distorted octa-hedral geometry. Within the anionic ligand, the pyridine ring is oriented at a dihedral angle of 49.54 (10)° with respect to the benzene ring. The carboxyl-ate group of the anionic ligand is not involved in coordination but is O-H⋯O hydrogen bonded to the coordinated and uncoordinated water mol-ecules. Weak inter-molecular C-H⋯O hydrogen bonding is also present in the crystal structure.

Project description:The complete mol-ecule of the title compound, [Cd(C(6)H(12)NOS(2))(2)(C(12)H(10)N(4))(2)], is generated by crystallographic inversion symmetry. The distorted octa-hedral trans-N(2)S(4) donor set for the Cd(2+) ion is defined by two symmetrically S,S'-chelating dithio-carbamate anions and two pyridine N atoms derived from two monodentate 4-pyridine-aldazine (or 4-{[(pyridin-4-yl-methyl-idene)hydrazinyl-idene}meth-yl]pyridine) mol-ecules [dihedral angle between the aromatic rings = 17.33 (8)°]. In the crystal, mol-ecules are connected into a supra-molecular chain via O-H⋯N hydrogen bonds involving the 4-pyridine-aldazine N atoms not involved in coordination to cadmium. Weak C-H⋯O and C-H⋯N links consolidate the packing.
