4-(Dimethylamino)pyridinium tribromide: whole molecule disorder of cation and anion
نویسنده
چکیده
In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the cation and the near-linear anion [Br-Br-Br = 179.41 (8)°] both show whole-mol-ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N-H⋯Br inter-action. The crystal studied was found to be a racemic twin, with a twin component of nearly 50%.

Redetermination of 4-(dimethylamino)pyridinium tribromide
In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the essentially planar cation (r.m.s. deviation = 0.006 Å) forms an N-H⋯Br hydrogen bond to one of the Br atoms of the almost linear anion [Br-Br-Br = 179.31 (2)°]. The crystal studied was found to be a racemic twin. The whole-mol-ecule disorder of the cation and anion about a twofold rotation axis described earlier [Ng (2009). Acta Cryst. E65, o1...

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...

In the title salt, (C(7)H(11)N(2))[SnCl(4)(C(10)H(6)NO(2))], the Sn(IV) atom is chelated by the N,O-bidentate carboxyl-ate ions and four chloride ions, showing a distorted octa-hedral SnNOCl(4) coordination. In the crystal, the cation and anion are linked by a pyridinium-carboxyl-ate N-H⋯O hydrogen bond.

The title salt, (C7H11N2)[FeCl4], consists of one essentially planar (the r.m.s. deviation for all non-H atoms being 0.004 Å) 4-(dimethyl-amino)-pyridinium cation and a tetra-hedral tetra-chloridoferrate(III) anion. The cations and anions are arranged in layers parallel to (010). Besides electrostatic inter-actions, the crystal packing features N-H⋯Cl and C-H⋯Cl hydrogen bonds between cations a...
