TL;DR: In this article, the crystal molecular structure of the manganese(III) complex, MnLC, was established by X-ray diffraction methods, and the structure was refined to the conventional agreement index R = 0.057 with 1880 observed reflections.

TL;DR: The mass spectrometric behavior of seven polydentate Schiff bases derived from the condensation of formyl or diformyl precursors (2,3-dihydroxy- or 2,5-dibenzaldehyde, 3-metoxy- or 3-ethoxy-salicylaldehyde), 3-formyl-salicyclic acid, 4-methoxy -or 4-chloro-2,6-diformylphenol) with 2-aminomethylpyridine have been investigated by fast atom bombardment

TL;DR: The mass spectrometric behavior of ten variously substituted mono- and bis-salicylaldimine derivatives has been studied by fast-atom bombardment and metastable-ion studies.
Abstract: The mass spectrometric behaviour of ten variously substituted mono- and bis-salicylaldimine derivatives has been studied by fast-atom bombardment and metastable-ion studies. In general, well detectable protonated molecules are present and fragmentation processes mainly related to aldimine chain cleavages are evidenced. Interesting cyclization reactions leading to particularly stable product ions are discussed.
