Catena-Poly[[(nitrito-?O,O')silver(I)]-?-1,2-bis-[1-(pyridin-4-yl)ethyl-idene]hydrazine-?N:N'].

ABSTRACT: The asymmetric unit of the title compound, [Ag(NO(2))(C(14)H(14)N(4))](n), contains half of the repeating formula unit (Z' = 1/2). The Ag(I) ion lies on a twofold rotation axis. The primary structure consists of a one-dimensional coordination polymer formed by the Ag(I) ions and the bipyridyl azine ligand in which there is an inversion center at the mid-point of the N-N bond. The nitrite anion inter-acts with the Ag(I) ion through a chelating ?(2) inter-action involving both O atoms. In the crystal, the coordination chains are parallel and inter-act through Ag?? [3.220?(2)?Å] and ?-? [3.489?(3)?Å] inter-actions.

Project description:In the title coordination polymer, [Cu(2)I(2)(C(14)H(14)N(4))(C(18)H(15)P)(2)](n), the Cu(I) atom is coordinated by two I atoms, one P atom and one N atom in a fairly regular tetra-hedral arrangement. A crystallographic inversion centre generates a Cu(2)I(2) diamond with a Cu-Cu separation of 3.0120?(5)?Å. The complete N,N'-(1-pyridin-4-yl-ethethyl-idene)-hydrazine mol-ecule is also generated by inversion symmetry, and this bridging ligand leads to [011] polymeric chains in the crystal structure.

Project description:The asymmetric unit of the title compound, C(16)H(14)N(4)O(4), contains one half-mol-ecule of (nitro-phen-yl)ethanimine and the complete mol-ecule is generated by a crystallographic inversion centre.

In the crystal, C-H?O inter-actions link the molecules to form sheets that lie parallel to (10-4).

Project description:In the title compound, C(16)H(14)Br(2)N(2), the complete molecule is generated by a crystallographic twofold axis.

Each of these N/N/C/C planes makes a dihedral angle of 63.81?(10)° with the adjacent benzene ring. In the crystal, the mol-ecules are arranged into a layer parallel to the ac plane through C-H?? inter-actions. C?Br short contacts [3.4032?(18)-3.5969?(19)?Å] are also observed.

catena-Poly[[[bis-(methanol-?O)lead(II)]-?-N'-[1-(pyridin-2-yl-?N)ethyl-idene]isonicotinohydrazidato-?N',O:N] perchlorate].

Project description:The Pb(II) atom in the polymeric title compound, {[Pb(C(13)H(11)N(4)O)(CH(3)OH)(2)]ClO(4)}(n), is coordinated by an N'-[1-(pyridin-2-yl-?N)ethyl-idene]isonicotinohydrazidate ligand via O,N,N'-donors and simultaneously bridged by a neighbouring ligand via the isonicotinoyl N atom; two additional sites are occupied by methanol O atoms. The resultant supra-molecular chain is a zigzag along the c axis. The Pb(II) atom is seven-coordinated within an N(3)O(3) donor set and a lone pair of electrons, which defines a ?-pentagonal-bipyramidal coordination geometry with the pyridine N and lone pair in axial positions. The supra-molecular chains are linked into the two-dimensional array via inter-molecular Pb?N [3.020?(4)?Å] inter-actions. Layers stack along the a axis, being connected by O-H?O hydrogen bonds formed between the coordinated methanol mol-ecules and perchlorate anions.

Project description:The reaction of manganese seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) leads to the title compound, {[Mn(NCSe)2(C12H12N2)(CH3OH)2]·C12H12N2} n . The Mn(II) cation is coordinated by two N-bonded seleno-cyanate anions, two bpa ligands and two O-bonded methanol mol-ecules, within a slightly distorted octa-hedral geometry. The Mn(II) cations and the non-coordinating N-donor ligands are located on centers of inversion while the coordinating N-donor co-ligands are located on a twofold rotation axis. In the crystal, the Mn(II) cations are linked into chains along the c-axis direction by the bpa ligands. The chains are further connected via a non-coordinating bpa ligand into layers parallel to (3-10) via O-H?N hydrogen-bonding inter-actions.

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.
