In the title hydrated mol-ecular salt, C7H11N2 (+)·C7H6NO2 (-)·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2 (-) group in the anion is 8.5 (2)°. In the crystal, the cation forms an N-H⋯O hydrogen bond to the anion and the anion forms two N-H⋯O hydrogen bonds to adjacent water mol-ecules.(More)
In the anion of the title salt, C2H6NO2 (+)·C7H5O6S(-), the dihedral angle between the carb-oxy-lic acid group and the benzene ring is 5.02 (12)°. In the crystal, the anions are linked into inversion dimers through pairs of O-H⋯O hydrogen bonds between the carb-oxy-lic acid groups and sulfonate O atoms. A pair of C-H⋯O inter-actions is also observed within(More)
In the title molecular salt, C6H6N3 (+)·C7H7O3S(-), the components are linked by N-H⋯O hydrogen bonds into zigzag chains along [100]. These chains are further connected by weak C-H⋯O, C-H⋯π and π-π (centroid-to-centroid distances = 3.510, 3.701 and 3.754 Å) inter-actions into a three-dimensional network.
Flip flops are the fundamental building blocks for all sequential circuits. Data transition look ahead D flip flop consumes less power than the conventional D Flip flop. The power consumption of CMOS LSI's is a very important issue these days. Here we propose a modified data transition D flip flop which consumes less power than existing data transition D(More)
D flip flops are the basic memory element which is used in many of the applications. Due to increase in demand of portable devices the research in low power has tremendously increased. In this we have discussed about the existing 8T latch and proposed a new 9T flip flop with that latch which has reduced area and power when compared to the existing ones.(More)
The asymmetric unit of the title compound, C6H5N3·C7H6O3, comprises independent benzotriazole and 4-hydroxybenzoic acid molecules. The dihedral angle between the benzene ring and the benzotriazole ring system is 15.18 (7)°. The mean plane of the carb-oxyl group is twisted at an angle of 18.55 (1)° with respect to the benzene ring. The crystal structure is(More)
In the title compound, CH5N2O(+)·C7H5O6S(-), the dihedral angle between the benzene ring and the mean plane of the uronium cation is 76.02 (8)°. The carboxyl group in the anion is twisted by 1.47 (9)° from the benzene ring. In the crystal, the cation is linked to the anion by weak O-H⋯O and N-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid(More)
