[(2-Morpholinoethyl)(2-pyridylmethylene)amine]dithiocyanatozinc(II)

Abstract

The title compound, [Zn(NCS)2(C12H17N3O)], was prepared by the reaction of zinc acetate with pyridine-2-carbaldehyde, 2-morpholinoethyl­amine and ammonium thio­cyanate in an ethanol solution. The ZnII atom is five coordinate with a distorted trigonal–bipyramidal geometry, coordinating with three N atoms of the Schiff base (2-morpholinoeth­yl)(2-pyridylmethyl­idene)amine and two N atoms from two thio­cyanate ligands. The morpholine ring adopts a chair configuration.

Bis(2-methoxy-6-{[2-(methylammonio)ethyl]iminomethyl}phenolato)thiocyanatozinc(II) thiocyanate hemihydrate

“…The NH 2 + hydrogen atoms are involved in hydrogen bonding with the ligand O-atoms which partially determines the conformation of the ligands. The Zn-O and Zn-N bond lengths [1.977 (4) -1.979 (4) Å and 2.001 (6) -2.135 (5) Å, respectively] are comparable to the values in similar complexes (Li et al, 2008;Eltayeb et al, 2008;Zhang & Wang, 2007;Cai, 2009).…”

{2-Morpholino-N-[1-(2-pyridyl)ethylidene]ethanamine-κ3N,N′,N′′}bis(thiocyanato-κN)zinc(II)

“…The Schiff base ligand in the molecules acts as an N,N′,N"-tridentate chelate, along with the N atoms of two isothiocyanate ligands this makes penta-coordiante zinc(II) complexes. Similar coordination environment has been reported in related mixed-ligand zinc(II) complexes (Cai, 2009;Chen et al, 2005). The geometry of the two present complexes can be determined by using the index τ = (β-α)/60, where β is the largest angle and α is the second one around the metal center.…”

“…Schiff bases are interesting ligands which form a large number of complexes with metal atoms (Costes et al, 2002;Erxleben, 2001;Lacroix et al, 1996;Odoko et al, 2006;Ali et al, 2006). The author has recently reported on the crystal structure of a zinc(II) complex with the Schiff base (2-morpholin-4-ylethyl)-(1-pyridin-2-ylmethylidene)amine (Cai, 2009). As a continuous of our work in this area, we report here on the crystal structure of the title copper(II) complex ( Fig.…”
