The reaction of dimethylchloramine with an excess of iodomethane at room temperature gives a yellow crystalline material which has been shown by low temperature X-ray analysis to contain the [Me4N]+ cation and the novel anion [Me2N(ICl)2]– which can be regarded as having the structure (A), analogous to [I5]–, with [NMe2]– as a pseudo-halide ion.
