[2,6-Bis(dimethyl-amino-meth-yl)phen-yl]selenium bromide monohydrate.


ABSTRACT: In the title hydrated molecular salt, C(12)H(19)N(2)Se(+)·Br(-)·H(2)O, the two independent bromide anions lie on a twofold rotation axis. Strong intra-molecular N→Se inter-actions [2.185 (3) and 2.181 (3) Å] are established by both N atoms of the organic group in the cation, in trans positions to each other, with an N-Se-N angle of 161.6 (1)°, resulting in a T-shaped (C,N,N')Se core. In the crystal, dimeric associations are formed by Br⋯Se [3.662 (2) Å] and Br⋯H inter-actions [2.56 (6) and 2.63 (7) Å] involving two bromide anions, two cations and two water mol-ecules.
