4-(Dimethylamino)pyridinium tribromido{3-[bromo/hydro(0.9/0.1)]-4-(dimethylamino)pyridine-κN 1}cobaltate(II)

چکیده
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.

In the title complex, [Zn(N3)2(C7H10N2)2], the Zn(II) atom is coordinated by two N atoms from two 4-(dimethyl-amino)-pyridine (DMAP) ligands and by two N atoms from two azide anions in a distorted tetra-hedral coordination geometry. In the crystal, weak C-H⋯N hydrogen bonds between the DMAP and azide ligands link these discrete complex mol-ecules into a three-dimensional supra-molecular network.
