| Abstract: A new dinuclear azido-bridged copper(Ⅱ) complex [Cu2L2( μ1,3-N3)2] bearing crystallographic two-fold rotation axis symmetry has been synthesized from the tridentate Schiff base ligand 5-(ethylmethylamino)-2-[(2-morpholin-4-ylethylimino)methyl]phenol (HL) and sodium azide with copper(Ⅱ) acetate in methanol. The complex was characterized by elemental analyses, infrared spectroscopy, and X-ray single crystal determination. Crystal of the complex is crystallize as orthorhombic space group P21212, with a=0.974 6(1), b=1.378 4(2), c=1.504 1(2) nm, V=2.023 3(5) nm3, Z=2, R1=0.063 8, wR2=0.166 8. Thermal stability and magnetic property of the complex were studied. CCDC: 890948. |
