Transition-metal complexes of imidazole ImH (C3H4N2) are relevant for the study of metalloenzymes and protein folding. Moreover, these materials could lead to potential applications such as electrochromic displays, photovoltaic cells and biomaterials. A series of metal-imidazole complexes of general formula + - x Mx Im (where x = 1, 2, M = Ag, Zn, Co, Cu and Im- = C3H3N2 is the deprotonated form of ImH) was synthesized and comprehensively studied as model materials for metalloproteins and molecular magnets. Their atomic dynamic properties were investigated with X-ray diffraction, XANES, EXAFS, vibrational spectroscopy and magnetic techniques. Metal-ligand bond lengths and force constans were estimated. The relationship between these structural data and rich spin dynamics revealed for M = Cu, Co bis-imidazolate compounds is discussed.
