triazine Chem.|traɪˈæzaɪn|
[f. tri- 5 a + azote + -ine5.]
A general term, invented by Widman (1888), for compounds the molecules of which contain a cyclic group consisting of three carbon and three nitrogen atoms.
These may be arranged in three ways: (a) the consecutive or vicinal form, also called osotriazine; (b) the unsymmetrical; (c) the symmetrical, also called cyanidine: thus (1) N{btr1}N.C{bbr1}{bbr1}N.C.{btr1}C , (2) N{btr1}N.C{bbr1}{bbr1}C.C.{btr1}N , (3) N{btr1}C.N{bbr1}{bbr1}C.N.{btr1}C.
