6,6'-(Pyridine-2,6-di-yl)bis-(pyrrolo-[3,4-b]pyridine-5,7-dione).

ABSTRACT: The title compound, C(19)H(9)N(5)O(4), has crystallographically imposed twofold rotational symmetry. The asymmetric unit contains one half-mol-ecule. The crystal structure is stabilized by ?-? stacking of inversion-related pyrrolo-[3,4-b]pyridine rings, with a centroid-centroid distance between stacked pyridines of 3.6960?(8)?Å. The dihedral angle between the central pyridine ring and the pyrrolo-pyridine side rings is 77.86?(2)° while the angle between the two side chains is 60.87?(2)°.

The title compound, C(19)H(9)N(5)O(4), has crystallographically imposed twofold rotational symmetry. The asymmetric unit contains one half-mol-ecule. The crystal structure is stabilized by π-π stacking of inversion-related pyrrolo-[3,4-b]pyridine rings, with a centroid-centroid distance between stacked pyridines of 3.6960 (8) Å. The dihedral angle between the central pyridine ring and the pyrrolo-pyridine side rings is 77.86 (2)° while the angle between the two side chains is 60.87 (2)°. ...[more]

Project description:In the title centrosymmetric tetra-nuclear complex, [Cu(4)I(4)(C(15)H(17)N(5))(2)], the two distinct Cu(I) atoms adopt similar tetra-hedral arrangements, each being ligated by two I atoms, and two N atoms from one 2,6-bis-(3,5-dimethyl-1H-pyrazol-1-yl)pyridine ligand. In the crystal, there are no hydrogen bonds present, and only very weak ?-? inter-actions are observed [centroid-centroid distance = 3.985?(4)?Å], which connect neighbouring tetra-nuclear units into a chain motif along the b axis.

(-)-N,N'-Bis[(1S,2R,5S)-6,6-dimethyl-bicyclo-[3.1.1]heptan-2-ylmeth-yl]pyridine-2,6-dicarboxamide monohydrate.

Project description:The title compound, C(27)H(39)N(3)O(2)·H(2)O, is a chiral pyridine-2,6-dicarboxamide derivative including cis-myrtanyl groups as amine substituents. The pyridine-2,6-dicarboxamide core approximates C(2) point symmetry and a solvent water mol-ecule lies on the pseudo-twofold axis. The water mol-ecule serves both as acceptor and donor for efficient hydrogen bonds involving N-H and C=O functional groups as donor and acceptor groups, respectively. As a result, each water mol-ecule in the crystal structure is tetra-hedrally bonded to three symmetry-related mol-ecules, forming a three-dimensional supra-molecular network. Such an arrangement is a common feature found in the majority of X-ray-characterized sym-metrically substituted pyridine-2,6-dicarboxamide derivatives.
