Gas-phase behavior of novel binuclear nickel(II) and cobalt(II) complexes with bridging phosphinato ligands under MALDI and ESI conditions

摘要

Transition metal complexescontaining two or more interconnected metal coordination centers are of high practical interest for different areas of applied chemistry, molecular biology and pharmacology. Mass spectrometry analysis is very attractive due its information content, sensitivity and a relatively small experimental time unlike the methods of X-ray crystal structure analysis and radiospectroscopy. Moreover, the application of mass-spectrometry for structural analysis of high spin state complexes is very promising due some limitations of nuclear magnetic resonance in case of paramagnetic samples.
