Pyridine-2,5-diamine.

ABSTRACT: In the title mol-ecule, C5H7N3, intra-cyclic angles cover the range 117.15 (10)-124.03 (11)°. The N atoms of the amino groups have trigonal-pyramidal configurations deviating slightly from the pyridine plane by 0.106 (2) and -0.042 (2) Å. In the crystal, the pyridine N atom serves as an acceptor of an N-H⋯N hydrogen bond which links two mol-ecules into a centrosymmetric dimer. Inter-molecular N-H⋯N hydrogen bonds between the amino groups further consolidate the crystal packing, forming a three-dimensional network.

2,5-Dibromo-pyridine.

Project description:In the title compound, C(5)H(3)Br(2)N, C-H⋯N hydrogen-bonding inter-actions and Br⋯Br inter-actions [3.9418 (3) and 3.8986 (3) Å] connect the mol-ecules into planar sheets stacked perpendicular to the b axis. In addition, pyrid-yl-pyridyl inter-sheet π-π stacking inter-actions [centroid-centroid distance = 4.12 (1) Å] result in a three-dimensional network.

catena-Poly[diimidazolium [bis-(?-pyridine-2,5-dicarboxyl-ato)bis-[diaqua-praseodymate(III)]]-bis-(?-pyridine-2,5-dicarboxyl-ato)].

Project description:The title compound {(C(3)H(5)N(2))(2)[Pr(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]}(n), has a chain structure featuring a dimeric unit consisting of two Pr(III) atoms within a dodecahedral environment. Each of the metal cations is coordinated by two N atoms and two O atoms from two pyridine-2,5-dicarboxyl-ate ligands, two O atoms from another two pyridine-2,5-dicarboxyl-ate ligands and two water O atoms. The Pr(III) ions are bridged by two ligands along the c axis, forming the dimeric unit, and these are connected by four ligands along the b axis, forming a chain. N-H?O and O-H?O hydrogen bonds are found in the structure.

2,2'-Azanediyl-diethanaminium pyridine-2,5-dicarboxyl-ate.

Project description:The crystal structure of the title compound, C(4)H(15)N(3) (2+)·C(7)H(3)NO(4) (2-), consists of diethyl-enetriaminium (2,2'-azanediyl-diethanaminium) cations and pyridine-2,5-dicarboxyl-ate anions, which are linked by N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds. C-H⋯π inter-actions are also observed. In the anion, the carboxyl-ate groups are oriented at dihedral angles of 11.04 (15) and 6.31 (14)° with respect to the pyridine ring.

catena-Poly[[[diaqua-iron(II)]-μ-pyridine-2,5-dicarboxyl-ato-[tetra-aqua-iron(II)]-μ-pyridine-2,5-dicarboxyl-ato] tetra-hydrate].

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.

N-(4-Fluoro-benz-yl)-3-nitro-pyridine-2,6-diamine.

Project description:In the title compound, C(12)H(11)FN(4)O(2), the pyridine ring is connected to a benzene ring by a -CH(2)-NH(2)- chain. The nitro group is twisted out of the pyridine ring plane [torsion angle O-N-C-C = 10.41 (10)°]. An intramolecular N-H⋯O hydrogen bond occurs. The fluoro-benzene ring is disordered over two positions [occupancy ratio = 0.59 (3):0.41 (3)]. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds stabilize the crystal structure.

Project description:The polymeric title compound, {(C(4)H(12)N(2))[Zn(C(7)H(3)NO(4))(2)(H(2)O)]·2H(2)O}(n), was obtained by the reaction of zinc(II) nitrate hexa-hydrate with the proton-transfer compound (pipzH(2))(py-2,5-dc) (where pipz is piperazine and py-2,5-dcH(2) is pyridine-2,5-dicarboxylic acid) in aqueous solution. Each Zn(II) atom is coordinated in a distorted octa-hedral geometry by four O atoms and two N atoms from one water mol-ecule and two (py-2,5-dc)(2-) ligands, which also act as bridging ligands between Zn(II) atoms. π-π Stacking inter-actions between two aromatic rings of (py-2,5-dc)(2-) fragments, with centroid-centroid distances of 3.4747 (7) and 3.7081 (7) Å are observed. The crystal structure is stabilized by O-H⋯O and N-H⋯O hydrogen bonds.
