2-Amino-6-(dimethylamino)pyridine-3,5-dicarbonitrile
The title compound, C(9)H(9)N(5), is slightly twisted from planarity, with a maximum deviation of 0.0285 (13) Å from the pyridine plane for the C atom bearing the amino group. The cyano groups are on different sides of the pyridine plane, with C- and N-atom deviations of 0.072 (3)/0.124 (4) and -0.228 (4)/-0.409 (5) Å from the pyridine plane. In the crystal, N-H⋯N and C-H⋯N hydrogen bonds conne...
متن کامل2-(Morpholin-4-yl)-6-(1H-pyrrol-1-yl)pyridine-3,5-dicarbonitrile
In the title compound, C(15)H(13)N(5)O, the morpholine ring adopts a chair conformation. The dihedral angle between the pyrrole ring and the pyridine ring is 28.93 (14)°. In the crystal, the molecules are linked by C-H⋯O hydrogen bonds occur, and aromatic weak π-π stacking [centroid-centroid separation = 4.178 (2) Å] and C-H⋯π inter-actions consolidate the packing.

In the title tricyano-nitrile compound, C(8)H(5)N(5), the N-substituted cyano-ethyl group is offset to the imidazole ring [dihedral angle = 75.41 (15)°].
متن کامل2-(Piperidin-1-yl)-6-(1H-pyrrol-1-yl)pyridine-3,5-dicarbonitrile
The piperidine ring of the title compound, C(16)H(15)N(5), adopts a chair conformation. The pyridine ring is essentially planar, with a maximum deviation of 0.035 (3) Å. The pyrrole and pyridine rings are almost coplanar, forming a dihedral angle of 3.48 (14)°. In the crystal, no classical hydrogen bonds were found. In the crystal, the molecules are linked by aromatic π-π stacking [centroid-cen...

This paper presents the development of a real-time microsensor-based monitoring system that can be used to detect and characterize volatile organic compounds in soil and groundwater. The system employs an array of polymer-based microsensors (chemiresistors) packaged in a waterproof housing that is designed to protect the sensor from harsh subsurface environments, including completely water-satu...
