N′-(4-Bromobenzylidene)quinoline-8-sulfonohydrazide
In the title compound, C(16)H(12)BrN(3)O(2)S, the dihedral angle between the planes of the almost planar (r.m.s. deviation = 0.0263 Å) quinoline group and the bromo-phenyl group is 87.4 (1)°. The torsion angle of the central S-N-N-C bridge is 144.8 (2)°. The amino group has an intra-molecular contact to the quinoline N atom. The structure is stabilized by one N-H⋯O and two C-H⋯O inter-molecular...
متن کاملN = 8 Supergravity 4 - point Amplitudes
We present the explicit expressions in N=8 supergravity for the bosonic 4-particle tree and 1-loop amplitudes including vectors and scalars. We also present the candidate 4point UV divergences in a form of helicity amplitudes, corresponding to 3-loop manifestly N=8 supersymmetric and Lorentz covariant counterterm. This may shed some light on the 3-loop finiteness of N=8 SG and on a conjectured ...
متن کامل4-Nitro-N-(8-quinolyl)benzamide
In the title compound, C(16)H(11)N(3)O(3), the amide group is twisted away from the plane of the quinoline benzene ring by 3.93 (5)°, but is twisted away from the nitro-benzene ring by 22.68 (4)°. A weak intra-molecular C-H⋯O hydrogen bond is observed. In the crystal structure, mol-ecules are linked into a chain along the a axis by inter-molecular C-H⋯O hydrogen bonds.
متن کاملNew Gauged N=8, D=4 Supergravities
New gaugings of four dimensional N = 8 supergravity are constructed, including one which has a Minkowski space vacuum that preserves N = 2 supersymme-try and in which the gauge group is broken to SU(3) × U(1) 2. Previous gaugings used the form of the ungauged action which is invariant under a rigid SL(8, R) symmetry and promoted a 28-dimensional subgroup (SO(8), SO(p, 8 − p) or the non-semi-sim...
متن کامل(E)-N′-(4-Nitrobenzylidene)-4-(8-quinolyloxy)butanohydrazide
In the title compound, C(20)H(18)N(4)O(4), conformation along the bond sequence linking the benzene and quinoline rings, which have a mean inter-planar dihedral angle of 2.7 (5)°, is trans-(+)gauche-trans-trans-(-)gauche-trans-trans. In the crystal structure, a pair of inter-molecular N-H⋯O hydrogen bonds links the mol-ecules into centrosymmetric cyclic R(2) (2)(8) dimers, which are aggregated ...
