4-(Dimethyl-amino)pyridinium tri-bromido-{3-[bromo/hydro-(0.9/0.1)]-4-(dimethyl-amino)pyridine-κN}cobaltate(II).

Bottom Line: In the anion, the Co(II) atom is coordinated in a distorted tetra-hedral geometry by three Br atoms and the pyridine N atom of a bromine-substituted 4-(dimethyl-amino)pyridine mol-ecule, whose formation probably results from an incomplete substitution (90%) catalysed by the Co(II) ion.One of the three bromine atoms bonded to the metal is disordered over two sites in a 0.9:0.1 ratio.An N-H⋯Br hydrogen bond connects the cation and anion.

ABSTRACT
The reaction of a cobalt(II) salt with 4-(dimethyl-amino)pyridinium hydro-bromide perbromide yielded the title compound, (C(7)H(11)N(2))[CoBr(3)(C(7)H(9.1)Br(0.9)N(2))]. In the anion, the Co(II) atom is coordinated in a distorted tetra-hedral geometry by three Br atoms and the pyridine N atom of a bromine-substituted 4-(dimethyl-amino)pyridine mol-ecule, whose formation probably results from an incomplete substitution (90%) catalysed by the Co(II) ion. One of the three bromine atoms bonded to the metal is disordered over two sites in a 0.9:0.1 ratio. An N-H⋯Br hydrogen bond connects the cation and anion.
