CYANOGEN

n. Si-a2n'o-.ie2n. Lat., cyanogenium (from icvavos, a bluish color, and yevvav, to engender). Fr., cyano gene. Ger., Cyan. It., cianogeno. Sp., cianogeno. A compound radicle, usually univalent, consisting of an atom of carbon and one of nitrogen united together. Symbol, CN or Cy. In its chemical relations it is analogous to bromine, chlorine, and iodine. There are several isomeric varieties of c. depending upon the mode, of connection of the elements: 1. True c., or carbo nitrile, C =E N, in which the free bond is attached to the carbon atom; the nitrogen, however, may be a pentad, and then there result trivalent compounds of the formula C = N= 2. If so cyanogen, or carb ammonium, C = N, in which the free bond is attached to the nitrogen, which is here a pentad. 3. Pseudo cyanogen, a trivalent radicle, = C = N-. In the free state c. consists of a double molecule, C2N2. See C. gas. [B, 4, 158, 270 (a, 24).] C. bromide. Fr., bromure de cyano gene. Ger., Bromcyan, Cyanbromiir. It., bromuro di cianogeno. Sp., bromuro de cianogeno. A compound of c. and bromine, CNBr Br C EE N, occurring as colorle cubical or acicular volatile crystals, which are very poisonous. [B, 4, 158 (a, 24).] C. chloride. Fr., chlorure de cyano gene. Ger.,flu iges Chlorcyan Cyanchloriir. It., cloruro di cianogeno. Sp., cloruro de cianogeno. A compound of c. and chlorine, CNC1 = C1 C=N; a mobile liquid, crystallizU2, blue; U3, lull; U4, full; U, urn; U, like (German). [s. 479]
