Abstract

A new hetero-trinuclear complex [Cu₂(μ-L) ₂Sr(NO₃)₂] has been synthesized and characterized by elemental analysis, IR, UV-Vis and X-ray crystallography, where L is a dianionic tetradentate Schiff base ligand with N₂O ₂ donor atoms. The X-ray structure indicates that the trinuclear complex adopts a bent structure for the three metal atoms, with a Cu1-Sr-Cu2 intramolecular angle of approximately 99.1°. In the complex, the two terminal Cu ions are situated in a distorted square planar geometry coordinated by two imine nitrogen atoms and two phenolato oxygen atoms from the Schiff base ligand. The two neutral CuL complexes are bonded to a Sr(II) ion. The geometry of central strontium atom is a distorted square antiprism formed by eight oxygen atoms, four oxygen atoms belonging to the two Schiff base ligands from two units of CuL and four oxygen atoms belonging to the two bidentate nitrate ions. The two bidentate nitrates are cis to each other.
