Sažetak
The title compound, [MoO2(L)(CH3OH)], crystallizes as a concomitant conformational trimorph. The occurrence domains, under which these forms can be prepared, separated, and/or interconverted, were explored and determined in terms of the crystallization conditions and solid-state reactions. Solvent-free reactions resulted in dissociation of coordinated methanol, producing two new complexes, monomeric [MoO2(L)] and polymeric [MoO2(L)]n. They both bind methanol molecule from its vapor, thus providing a pure α-form of the title complex. All forms have been characterized and compared to each other by a variety of methods including elemental analysis, Fourier transform IR, thermal methods, X-ray powder diffraction, and single-crystal X-ray structure determination.
