[2,6-Bis(dimethylaminomethyl)phenyl]- selenium bromide monohydrate

Abstract

In the title hydrated molecular salt, C12H19N2Se+·Br-·H2O, the two independent bromide anions lie on a twofold rotation axis. Strong intramolecular N--Se interactions [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 interactions [2.56 (6) and 2.63 (7) Å] involving two bromide anions, two cations and two water molecules.
