6-Methyl-N-(2-methyl-phen-yl)-3-phenyl-1,6-dihydro-1,2,4,5-tetra-zine-1-carbox-amide.

ABSTRACT: In the title compound, C(17)H(16)N(5)O, the central tetra-zine ring adopts an unsymmetrical boat conformation with the two C atoms as flagpoles. This compound can be considered as having homoaromaticity. The crystal structure is stabilized by inter-molecular C-H?O inter-actions between a benzene H atom and the carbonyl O atom.

3-Phenyl-6-(2-pyrid-yl)-1,2,4,5-tetra-zine.

Project description:The title compound, C(13)H(9)N(5), is the first asymmetric diaryl-1,2,4,5-tetra-zine to be crystallographically characterized. We have been inter-ested in this motif for incorporation into supra-molecular assemblies based on coordination chemistry. The solid state structure shows a centrosymmetric mol-ecule, forcing a positional disorder of the terminal phenyl and pyridyl rings. The mol-ecule is completely planar, unusual for aromatic rings with N atoms in adjacent ortho positions. The stacking observed is very common in diaryl-tetra-zines and is dominated by π stacking [centroid-to-centroid distance between the tetrazine ring and the aromatic ring of an adjacent molecule is 3.6 Å, perpendicular (centroid-to-plane) distance of about 3.3 Å].

Project description:The asymmetric unit of the title compound, C(8)H(14)N(6)O(2), contains two independent mol-ecules. In one mol-ecule, the amide-substituted N atoms of the tetra-zine ring deviate from the plane [maximum deviation = 0.028?(1)?Å] through the four other atoms in the ring by 0.350?(2) and 0.344?(2)?Å, forming a boat conformation, and the mean planes of the two carboxamide groups form dihedral angles of 10.46?(13) and 20.41?(12)° with the four approximtely planar atoms in the tetra-zine ring. In the other mol-ecule, the amide-substituted N atoms of the tetra-zine ring deviate from the plane [maximum deviation = 0.033?(1)?Å] through the four other atoms in the ring by 0.324?(2) and 0.307?(2)?Å, forming a boat conformation, and the mean planes of the two carboxamide groups form dihedral angles of 14.66?(11) and 17.08?(10)° with the four approximately planar atoms of the tetra-zine ring. In the crystal, N-H?O hydrogen bonds connect mol-ecules to form a two-dimensional network parallel to (1-1-1). Intra-molecular N-H?N hydrogen bonds are observed.
