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...
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 cry...
The title compound, C11H12N2, is not planar due to the folding of the seven-membered ring. In the crystal, mol-ecules are packed opposite each other to minimize the electronic repulsion but the long inter-molecular distances indicate that no directional contacts are found.
