Synthesis and characterization of Mn+2, Co+2, Ni+2, Cu+2 and Zn+2 complexes with pyridinium salt. crystal structure of 1, 3, 5- trimethylpyridinium iodide

الملخص EN

A series of new complex salts of the type [A] 2 [MCl2I2] where A=1, 3, 5- trimethylpyridinium cation, M= Mn+2, Co+2, Ni+2,Cu+2 and Zn+2 were prepared by the reaction of the metal chloride and 1,3,5-trimethylpyridinium iodide in (1:2) molar ratio and characterized by elemental analysis, molar conductance, IR, Uv / Vis., spectral studies and magnetic measurements.

The crystal structure of 1, 3, 5-trimethylpyridinuim iodide was determined by single crystal x-ray crystallography.

The structure of the anion part and a 1, 3, 5- trimethylpyridinium cation which crystallizes in the orthorhombic space group (Cmcm) with a = 8.9850(9), b =15.767 (2).

C = 6.9940 (6) A°, V = 990.82 (16) A°, Z = 4.

Which is on a crystallographic mirror plane? Perpendicular to C-axis except for methyl hydrogen atoms.

The anion and cation are connected through hydrogen bonds between I and the cation by hydrogen bonding, electrostatic interaction and weak π-π interaction are also expected.
