Synthesis and Crystal Structure of Dinuclear Copper Complex[Cu（CH2O（C6H4）N=C（C6H4）O）（Py]2

1 INTRODUCTION Synthesis of transition metal complexes with Schiff-base has been a subject of considerable importance [1,2]. They are not only good complexing agents for Schiff-base, but also good bactericide and antitumour agent [3,4]. At present, there is a spectacular growth in this field. Recently, some bridged binuclear complexes have received much attention on account of their biological relevance and condensed-phase magnetic properties[5,6]. Especially, the complexes containin…

Synthesis and Crystal Structure of Dinuclear Copper Complex [Cu(CH2O(C6H4)N=C(C6H4)O)(Py)]2

The complex [Cu2L2(Py)2] (H2L=2-aminobenzoic alcohol condensation salicylaldehyde) was obtained. A single-crystal X-ray study shows that the complex is a binuclear compound (Cu2C38H32N4O4). The coordination geometry about each copper atom is best described as a distorted square pyramid. The compound [Cu2L2(Py)2] belongs to monoclinic system with space group P21, lattice constants: a = 10.3881(1), b = 17.9724(1), c = 17.5800(2) ? b =90.4880(1), V= 3282.05(5) 3, Z= 4, Mr =735.75, Dc=1.489 g/cm3, m= 1.344mm-1, F(000) = 1512, R=0.0519, wR=0.1092 for 6725 reflections with I >2s(I). The distances between Cu(II) and O atoms are range from 1.898(6) to1.976(5)? between Cu(II) and N atoms are range from 1.990(6) to 2.369(7)? The Cu(1)Cu(2) bond length is 3.024(4) ?
