The asymmetric unit of the title salt, C4H12N2 (2+)·2C6H6NO3S(-), consists of half a piperazindiium dication, located about an inversion centre, and a 4-amino-benzene-sulfonate anion. The piperazine ring adopts a chair conformation. In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework.… (More)
The title compound, C24H27NO2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules have very similar conformations and each exhibits an intra-molecular C-H⋯π inter-action. The central piperidine rings adopt boat conformations and the p-tolyl rings are inclined to the mean plane of the piperidine ring by 71.21… (More)
In the title compound, C12H8BrClN2O3, the furan ring makes a dihedral angle of 17.2 (2)° with the six-membered ring. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into chains running along the c-axis direction. The crystal packing is additionally stabilized by C-H⋯O… (More)
— A Fault tolerant reversible logic has gained importance as they consume low power and less heat dissipation. The benefits of logical reversibility can be gained only after employing physical reversibility. Every future technology will have to use reversible gates in order to reduce power. This paper proposed a new fault tolerant reversible 4*4 RR-gate… (More)
In the title compound, C(20)H(22)O(5)S, the dihedral angle between the mean planes through the thio-phene and benzene rings is 75.2 (1)°. The meth-oxy group is essentially coplanar with the benzene ring, the largest deviation from the mean plane being 0.019 (2) Å for the O atom. The malonate group assumes an extended conformation.
In the title compound, C(21)H(17)N(5)·H(2)O, the dihedral angles between the acridine ring system and the imidazole rings are 78.8 (1) and 71.2 (1)°. The crystal packing is stabilized by O-H⋯N, C-H⋯O, C-H⋯π and π-π inter-actions [centroid-centroid separations = 3.732 (1) and 3.569 (1) Å].
In the title compound, C(13)H(11)NO(3)S, the two aromatic rings are oriented at an angle of 88.18 (8)°. Intra-molecular N-H⋯O and C-H⋯O hydrogen bonds are observed, each of which generates an S(6) ring motif. In the crystal, mol-ecules are linked into C(7) chains along  by inter-molecular C-H⋯O hydrogen bonds. The structure is further stabilized by… (More)
In the title compound, C(14)H(15)NO(6), the ethoxy-carbonyl groups adopt extended conformations. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of C-H⋯O hydrogen bonds with a R(2) (2)(20) motif.
