Diazinanes or hexahydrodiazines are a class of nitrogen-containing heterocycles consisting of a saturated four-carbon, two-nitrogen ring. They exist in three isomeric forms depending on the relative position of the two nitrogen atoms, with 1,4-diazinanes being common.

Structure

The diazinanes have six-membered cyclohexane-like ring but with two carbon atoms replaced by nitrogen atoms. The three isomers of triazinane are distinguished by the positions of their nitrogen atoms, and are referred to as 1,2-diazinane, 1,3-diazinane, and 1,4-diazinane (more commonly called piperazine).
