BeschreibungResearch Paper from the year 2012 in the subject Chemistry - Anorganic Chemistry, University of Mosul (Dental college), language: English, abstract: 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 ¿-¿ interaction are also expected.
