Dichlorido{2-morpholino-N-[1-(2-pyrid-yl)ethyl-idene]ethanamine-?N,N',N''}zinc(II).

ABSTRACT: In the title compound, [ZnCl(2)(C(13)H(19)N(3)O)], the Schiff base ligand acts as an N,N',N''-tridentate chelating agent, making two five-membered rings with the Zn(II) ion. The metal atom is five-coordinated by the Schiff base ligand and two Cl atoms in a distorted square-pyramidal geometry. An intra-molecular C-H?Cl inter-action occurs. In the crystal, adjacent mol-ecules are linked together via C-H?Cl hydrogen-bonding and long range C-H?O and C-H?Cl inter-actions into a three-dimensional network.

Dichlorido{2-hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propanohydrazide-κN,N',O}zinc(II) hemihydrate.

Project description:The title compound, [ZnCl(2)(C(10)H(12)N(4)O(2))]·0.5H(2)O, was readily prepared by the reaction between ZnCl(2) and 2-hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propanohydrazide. The Zn atom has a distorted trigonal-bipyramidal geometry with two Cl atoms and one azomethine N atom in the equatorial plane and one pyridine N atom and one amide O atom in the axial positions. In the crystal structure, complex mol-ecules are connected in pairs by N-H⋯Cl hydrogen bonds, formed between the amide NH of one mol-ecule and the Cl atom of a neighboring one. Mol-ecular pairs are connected by hydrogen bonds involving the uncoordinated water mol-ecule, which lies on a twofold axis.
