چکیده

The title compound, C(19)H(13)N(5)O(3), can be obtained from the corresponding α-amido-α-amino-nitrone in a reaction with biphenyl-2,2'-diamine. The amido-amidine core has distinctive geometrical parameters including: an outstandingly long Csp(2)-Csp(2) single bond of 1.5276 (13) Å and an amidine N-C-N angle of 130.55 (9)°. Intra-molecular N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds occur. In the crystal, mol-ecules form layers parallel to (001) via weak inter-molecular C-H⋯N inter-actions. The layers are linked via N-H⋯O hydrogen bonds and π-π inter-actions along [001] [benzene-pyridine centroid-centroid distance = 3.672 (2) Å].

The seven-membered ring in the title compound, C(28)H(22)N(2)S, has a two-coordinate N atom as well as a three-coordinate N atom. The ring adopts a boat-shaped conformation with two C atoms of one methyl-phenyl ring as the stern and the three-coordinate N atom as the prow. The N,N-dimethyl-ethane-thio-amide fragment is nearly planar (r.m.s. deviation = 0.049 Å); the phenyl ring of the benzene-c...

Salt forms of the pharmaceutical amide dihydrocarbamazepine.

Carbamazepine (CBZ) is well known as a model active pharmaceutical ingredient used in the study of polymorphism and the generation and comparison of cocrystal forms. The pharmaceutical amide dihydrocarbamazepine (DCBZ) is a less well known material and is largely of interest here as a structural congener of CBZ. Reaction of DCBZ with strong acids results in protonation of the amide functionalit...
