N,N'-Bis(5-bromo-pyridin-2-yl)methane-diamine.

ABSTRACT: The V-shaped title compound, C(11)H(10)Br(2)N(4), lies on a crystallographic twofold rotation axis which passes through the central C atom. In the crystal, an infinite tape motif, which propagates in the a-axis direction, is formed by inversion-related N-H⋯N hydrogen-bonding inter-actions. The structure confirmed the identity of the compound as a reaction side product.

N,N'-Dimethyl-N,N'-bis-(pyridin-2-yl)methane-diamine.

Project description:The title compound, C(13)H(16)N(4), consists of two pyridine rings which are linked by an N,N'-dimethyl-methane-amine chain. The pyridine rings adopt a twist conformation and the dihedral angle between them is 60.85 (5)°. The crystal packing is stabilized by weak C-H⋯π inter-actions.

5-Bromo-N-[(E)-(6-bromo-pyridin-2-yl)methyl-idene]pyridine-3,4-diamine.

Project description:The title compound, C(11)H(8)Br(2)N(4), is a Schiff base obtained from 6-bromo-picolinaldehyde and 5-bromo-pyridine-3,4-diamine. The mol-ecule has an E configuration about the C=N bond and the dihedral angle between the two pyridine rings is 14.02 (1)°. The observed conformation is stabilised by an intramolecular N-H⋯N hydrogen bond. In the crystal, mol-ecules are stacked along the b axis and are linked through N-H⋯N hydrogen bonds into chains along the c axis.

N,N'-Bis[1-(pyridin-2-yl)-ethyl-idene]benzene-1,4-diamine.

Project description:In the title compound, C(20)H(18)N(4), the benzene ring lies about an inversion center. The central benzene-1,4-diamine unit is connected to two pyridine rings by the C=N imine bonds. The dihedral angle between the benzene and pyridine rings is 82.9 (1)°.

N,N'-Bis(pyridin-2-yl)benzene-1,4-diamine-quinoxaline (2/1).

Project description:The asymmetric unit of the title compound, 2C(16)H(14)N(4)·C(8)H(6)N(2), consits of one mol-ecule of N,N'-bis-(pyridin-2-yl)benzene-1,4-diamine (PDAB) and one half-mol-ecule of quinoxaline (QX) that is located around an inversion centre and disordered over two overlapping positions. The PDAB mol-ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N bonds of the 2-pyridyl-amine units. In the crystal, these self-complementary units are N-H⋯N hydrogen bonded via a cyclic R(2) (2)(8) motif, creating tapes of PDAB mol-ecules extending along [010]. Inversion-related tapes are arranged into pairs through π-π stacking inter-actions between the benzene rings [centroid-centroid distance = 3.818 (1) Å] and the two symmetry-independent pyridine groups [centroid-centroid distance = 3.760 (1) Å]. The QX mol-ecules are enclosed in a cavity formed between six PDAB tapes.

N,N'-Bis(pyridin-2-yl)benzene-1,4-diamine-naphthalene (2/1).

Project description:The asymmetric unit of the title compound, C(10)H(8)·2C(16)H(14)N(4), consists of one mol-ecule of N,N'-bis-(pyridin-2-yl)benzene-1,4-diamine (PDAB) and one half of the centrosymmetric naphthalene mol-ecule. The PDAB mol-ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N bonds of the 2-pyridyl-amine units. In the crystal, N-H⋯N hydrogen bonds between the PDAB mol-ecules generate a cyclic R(2) (2)(8) motif, leading to the formation of PDAB tapes extending along [100]. The tapes are arranged into (010) layers and the naphthalene mol-ecules are enclosed in cavities formed between the PDAB layers.

Bis[?-N-(pyridin-2-ylmeth-yl)pyridin-2-amine-?N:N']disilver(I) bis(trifluoro-methane-sulfonate).

Project description:In the binuclear title compound, [Ag(2)(C(11)H(11)N(3))(2)](CF(3)O(3)S)(2), the complex cation is centrosymmetric, with the unique Ag(+) cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridin-2-ylmeth-yl)pyridin-2-amine ligands in a geometry slightly distorted from linear [N-Ag-N 161.02?(7)°]. This set-up leads to the formation of a 14-membered cyclic dimer. The two pyridine rings coordinated to the Ag(+) cation are tilted by 80.19?(7)° with respect to each other. Inter-molecular N-H?O hydrogen-bonding inter-actions between the cyclic dimer and the anion exist. A two-dimensional network parallel to the ac plane is constructed by three weak Ag?(O,N) inter-actions as well as an F?F contact of 2.890?(4)?Å.

A third polymorph of N,N'-bis-(pyridin-2-yl)benzene-1,4-diamine.

Project description:A third polymorph of the title compound, C(16)H(14)N(4), has been obtained. The mol-ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N bonds of the 2-pyridyl-amine units. Like in the triclinic form [Bensemann et al. (2002 ▶). New J. Chem.26, 448-456], the recognition process between 2-pyridyl-amine units takes place through formation of a cyclic R(2) (2)(8) hydrogen-bond motif, leading to the creation of tapes parallel to [001].

Bis{N-methyl-N'-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine}-zinc bis-(perchlorate).

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:The title compound, C(25)H(22)Br(2)O(2), crystallizes with two mol-ecules in the asymmetric unit. In each independent mol-ecule, the two naphthalene ring systems are nearly perpendicular to one another, with dihedral angles of 85.6?(1) and 86.2?(1)°. The crystal structure is stabilized by C-H?? inter-actions, and inter- and intra-molecular C-H?O and C-H?Br hydrogen bonds.
