Study of Crystal Structures of the [B10Cl10]2– Anion with Imidazolium Cations

A new method for the synthesis of imidazolium salts of the perchlorinated closo -decaborate anion (RMIM) 2 [B 10 Cl 10 ] (R = H, n -Et, n -Bu, n -C 8 H 17 ) has been proposed. The synthesis of these compounds can be carried out by simple metathesis reactions between the potassium salt of the decachl...

Description
Summary:A new method for the synthesis of imidazolium salts of the perchlorinated closo -decaborate anion (RMIM) 2 [B 10 Cl 10 ] (R = H, n -Et, n -Bu, n -C 8 H 17 ) has been proposed. The synthesis of these compounds can be carried out by simple metathesis reactions between the potassium salt of the decachloro- closo -decaborate anion K 2 [B 10 Cl 10 ] and chlorides of imidazolium derivatives. The crystal packings and intermolecular interactions in compounds (EMIM) 2 [B 10 Cl 10 ] and (BMIM) 2 [B 10 Cl 10 ] have been studied using X-ray diffraction and Hirshfeld surface analysis. The [B 10 Cl 10 ] 2– anions in the crystal lattice of these compounds are linked by a network of weak Cl···Cl interactions with a distance between chlorine atoms of 2.246–3.623 Å.
