A series of lithium and sodium iminophenoxide complexes have been successfully synthesized and characterized by X-ray crystallography and investigated as catalysts for the ring opening polymerization of L-lactide. The nature and steric bulk of the ligands coordinated to the central metal ions greatly influence the catalytic properties. Complexes with(More)
In the title centrosymmetric dimeric Zn(II) complex, [Zn(2)(C(27)H(27)N(4)O)(2)(C(7)H(7)O)(2)], the Zn(II) center is coordinated by two N atoms and one O atom of the ketiminate ligand and two bridging O atoms of the benzyl-alkoxy groups. The geometry around the Zn(II) ions is distorted trigonal-bipyramidal.
A series of calcium complexes supported by NNO-tridentate ketiminate ligands have been synthesized and characterized. X-ray structural studies indicate that these complexes bear a mononuclear feature with hexa-coordinated calcium centers bonding to two ketiminate ligands. Polymerization of L-lactide catalyzed by these complexes proceeds rapidly and well(More)
The monomeric title complex, [Zn(C14H12NOS)2]·2CHCl3 or L2Zn·2CHCl3, where L is the 2-({[2-(methyl-sulfan-yl)phen-yl]imino}-meth-yl)phenolate anion, may be obtained by the reaction of LZnEt with benzyl alcohol or by the reaction of two equivalents of LH with ZnEt2 in tetra-hydro-furan. The Zn atom, located on a twofold axis, is four-coordinated in a(More)
Structurally diverse copper acetate complexes based on NNO-tridentate Schiff-base ligands were synthesized and characterized as mono-, di-, and trinuclear complexes with respect to varied ancillary ligands. Treatment of the ligand precursors (L(1)-H = 2-(1-((2-(dimethylamino)ethyl)imino)ethyl)-4-methylphenol, L(2)-H =(More)
