dc.description.abstractEnTwo new coordination complexes {[(<b>L</b>)Cu<sub>2</sub>('-<b>L</b>)(NO<sub>3</sub>)(CH<sub>3</sub>OH)<sub>0.3</sub>(H<sub>2</sub>O)<sub>0.7</sub>]<b>·</b>NO<sub>3</sub>}[Cu(<b>L</b>)(NO<sub>3</sub>)(CH<sub>3</sub>OH)] (<b>1</b>) and [Mn<sub>2</sub>(-<b>L</b>)<sub>2</sub>(H<sub>2</sub>O)(<sub>1</sub>-N<sub>3</sub>)<sub>2</sub>(CH<sub>3</sub>OH)] (<b>2</b>) derived from (<i>E</i>)-<i>N</i>-(2-hydroxy-3-methoxybenzylidene)acetohydrazide [<b>LH</b>] have been synthesized. The new potentially tetradentate ONOO donor hydrazone ligand [<b>LH</b>] has shown considerable metal ion selective phenoxo bridging in <b>1</b> and <b>2</b>. It has coordinated copper(II) ions in its tridentate as well as in tetradentate fashion whereas for manganese(II) ions it solely showed its tetradentate character. In <b>1</b> the two adjacent pentacoordinate copper(II) centers are connected by a rare single phenoxo linkage of the hydrazone ligand whereas <b>2</b> is a doubly phenoxo-bridged heptacoordinated manganese(II) dinuclear species. The 3D supramolecular networks of <b>1</b> and <b>2</b> have resulted from extensive H-bonding interactions in the respective complexes. Structural variations observed for <b>1</b> and <b>2</b> have been described by performing single-crystal X-ray analysis. The ligand and the complexes are characterized by elemental analyses, IR, UV/Vis and <sup>1</sup>H NMR spectroscopy. Cryomagnetic investigations, DFT studies and EPR analysis, of <b>1</b> and <b>2</b> have also been studied in detail.
