Crystal structures of the N-salicylidene– L-serinatoaquacopper(II) monohydrate and its ternary derivative with 2-aminopyridine

The complexes [Cu(Sal–( L-Ser))H 2O]⋅H 2O 1 and [Cu(Sal–Ser)(2-amino pyridine)] 2 have been prepared and their crystal structures determined. In 1 the copper(II) has a square-pyramidal geometry, being coordinated to the tridentate Sal–( L-Ser) Schiff base ligand and the oxygen atom (O(16)) of one wa...

Description
Summary:The complexes [Cu(Sal–( L-Ser))H 2O]⋅H 2O 1 and [Cu(Sal–Ser)(2-amino pyridine)] 2 have been prepared and their crystal structures determined. In 1 the copper(II) has a square-pyramidal geometry, being coordinated to the tridentate Sal–( L-Ser) Schiff base ligand and the oxygen atom (O(16)) of one water molecule occupying the corners of a square. The coordination sphere about the copper is completed by an axial O(12) atom of an hydroxyl group belonging to an adjacent complex unit. In the racemic ternary complex 2 the metal atom has a square-planar coordination with O,N,O atoms of the tridentate Sal–Ser dianion and the heterocyclic N atom of the 2-aminopyridine. Spectroscopic data are discussed.
