چکیده
The asymmetric unit of the title compound, C(5)H(9)N(3) (2+)·2Cl(-), contains two diprotonated 2,3-diamino-pyridine cations and four chloride anions. In the crystal structure, the anions and cations are connected by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by π-π inter-actions between pyridinium rings [centroid-centroid distance = 3.695 (1) Å].

THE STRUCTURE OF THE TITLE COMPOUND (COMMON NAME: amodiaquinium dichloride dihydrate), C(20)H(24)ClN(3)O(2) (+)·2Cl(-)·2H(2)O, was previously determined from powder diffraction data [Llinàs et al. (2006 ▶). Acta Cryst. E62, o4196-o4199]. It has now been refined from diffractometer data to a significantly higher precision. The dihedral angle between the quinoline and benzene rings is 54.57 (6)°....

Halide, Pyridine Complexes, Zinc, X-Ray Data Zinc dichloride reacts with aminomethylpyridine (AMP) to the corresponding 1:1 adduct 1, whereas ZnBr2 forms an ionic 1:2 complex of the type [(AMP)2ZnBr]+ Br~ 2, which loses one neutral coligand upon heating in M e-C (0)0E t to yield nearly insoluble (AMP)ZnBr2 3. The condensation reaction of these compounds with acetone yields propylideneaminomethy...
