Solid state syntheses and interconversion of new metal salts and their coordination compounds
The state of the art in crystal engineering and solid state chemistry were exploited to prepare new crystalline solids [H4biim][MCl4] complexes (M = Co, 1; Cu, 2; Zn, 3) and [MCl2(H2biim)] (M = Co, 4; Cu, 5; Zn, 6) by solid state methods. The crystalline salts [H4biim][MCl4] (M = Co, Cu, Zn) contain anionic metal complexes (perchlorometallate) which are hydrogen bonded to organic cations (H2biim) decorated with NH H-bond donor groups, are synthesized via various solid state methods and then dehydrochlorinated via thermal or mechanochemical methods to obtain the coordination compounds [MCl2(H2biim)]. X-ray single crystal structure determination, powder diffraction (XRDP), thermogravimetric and elemental analyses were used in the preliminary characterization of the new salts and the derived materials.
