Synthesis and characterization of heterometallic rings templated through alkylammonium or imidazolium cations.

ABSTRACT: We report the synthesis and structural characterization of a series of heterometallic rings templated via alkylammonium or imidazolium cations. The template and preference of each metal's coordination geometry can control the structure of heterometallic compounds, leading to octa-, nona-, deca-, dodeca-, and tetradeca-metallic rings. The compounds were characterized by single-crystal X-ray diffraction, elemental analysis, magnetometry, and EPR measurements. Magnetic measurements show that the exchange coupling between metal centres is antiferromagnetic. EPR spectroscopy shows that the spectra of {Cr₇Zn} and {Cr₉Zn} have S = 3/2 ground states, while the spectra of {Cr₁₂Zn₂} and {Cr₈Zn} are consistent with S = 1 and
