(Z,Z)-5-Chloro-1,1,1,6,6,6-hexafluoro-3,4-diazahexa-2,4-diene-2-amine, in which the amino group is conjugated with a chain double bond
摘要:
The asymmetric unit of the title compound, C4H2ClF6N3, contains two crystallographically independent molecules which have similar C=N-N=C configurations [torsion angles -153.8(7) and -153.6 (7)degrees]. Intermolecular hydrogen bonds between the amino H atoms and the diazine N atoms link the molecules into infinite chains along the ac diagonal [N...N 2.989(9), 3.05(1), H...N 2.22(6), 2.16(8) angstrom, N-H...N 156(7), 172(7)degrees].

The title molecule, C10H8F6N4, has been characterized crystallographically, thus establishing its isomeric form. This form has a C=N-N=C substructure with a torsion angle of 145 (1)-degrees about the N-N bond. There is an extensive hydrogen-bonding system, such that each molecule is doubly bonded to each of two neighbours, related to the first by different twofold axes.
