The LI provenance is then confronted with elemental impurities measured in the copper metal in order to confirm that the mineral assemblage of the potential ore source is compatible with the observed chemistry of the sample. All objects investigated in this study were chemically analysed by scanning...
A series of eight novel complexes of chloranilic acid (CA) with the first-row transition metals (M = Mn, Cr, Ni, Co) were prepared and characterised by single-crystal X-ray diffraction, IR spectroscopy and polycrystalline X-band electron spin resonance (ESR) spectroscopy. All studied ...
