N (1),N (2)-Di-methyl-ethane-1,2-diaminium dichloride.

The cation of the title salt, C4H14N2 (2+)·2Cl(-), is located on a crystallographic inversion center and is bis-ected by a mirror plane, with one quarter of the C4H14N2 (2+)·2Cl(-) formula unit being crystallographically unique. he chloride ions also sit on a mirror plane. The conformation of the cation is a regular straight-chain conformation with all non-H atoms in anti positions. In the crystal, hydrogen bonding between N-H groups and chloride anions yields a zigzag ladder-type structure along [010].
