Mono, di and heptanuclear metal(II) complexes based on symmetric and asymmetric tetradentate Salamo-type ligands: Syntheses, structures and spectroscopic properties

Crystal structure of tetrakis(methanol-κO)-bis{μ2-3-((4-methoxy-2-oxidobenzylidene)amino)-2-oxo-2H-chromen-4-olate-κ4 O,N;O′:O′}dizinc(II), C38H38Zn2N2O14

“…Schiff base (contain -C = N-group) as a class of ligands are known to coordinate with metal ions through the azomethine nitrogen atom [6,7]. And they can form all kinds of stable metal complexes [8,9], which have interesting structures and wide use in biochemistry [10,11].…”

Crystal structure of triethylammonium bis{3-(((3-oxidonaphthalen-1-yl)methylene)amino)-2-oxo-2H-chromen-4-olato-κ3 O,N,O′}manganese(III), C46H38MnN3O8

“…In particular, a series of coumarin-derived Schiff bases and their complexes were found to possess significant bioactivity [5]. Furthermore, Schiff base compounds are capable of forming all kinds of stable metal complexes [6][7][8], which are considered more and more important because their novelty structural, topological and widely using in the fields of biochemistry [9,10], magnetic properties [11,12], photophysical properties [13,14], molecular recognition [15,16] and so on. The asymmetric unit of the title compound consists of a Mn(III) ion, two ligand units and a triethylammonium counter cation.…”
