ABSTRACT
The title complex, [Cu(SO4)(C13H13N3)(H2O)]·4H2O, was obtained by mixing copper sulfate penta-hydrate and 2-(pyridin-2-yl)-N-(pyridin-2-yl-methyl-idene)ethanamine in eth-anol under reflux conditions. The Cu(II) ion shows a Jahn-Teller-distorted octa-hedral geometry, with equatorial positions occupied by three N atoms from the tridentate ligand (average Cu-N = 2.004â
Å) and one O atom from a bidentate sulfate anion [Cu-O = 1.963â
(2)â
Å]. The axial positions are occupied by one O atom from a coordinating water mol-ecule [Cu-O = 2.230â
(3)â
Å] and one weakly bonded O atom [Cu-O = 2.750â
(2)â
Å] from the bidentate sulfate ion. The complex mol-ecules are connected through O-Hâ¯O hydrogen bonds between the coordinating water mol-ecules and sulfate ions from neighboring complexes, forming a double chain parallel to the c axis. The chains are stabilized through additional hydrogen bonds by one of the non-coordinating water mol-ecules bridging between neighboring strands of the double chains. The remaining three water mol-ecules fill the inter-stitial space between the double chains and are involved in an intricate hydrogen-bonding network that consolidates the structure.
