| Abstract: | Dinuclear Cu(Ⅱ) complexes (Cu,LCl4). 2H2O and Cu2L'Cl4 are pre-pared and characterized by X-ray structure analysis. (Cu2I-Cl4). 2H2O, C20 H40N6Cu2Cl4O2, Mr=665. 54, monoclinic, 6 for 188l observed reflections with I>3(I). Cu2L'Cl4, C20H36N6Cu2Cl4, M.=629. 41, monoclinic, for 1330 observed reflections with I>3(I). In both complexes the stereo-chemistry about Cu(Ⅱ) is 5-coordinated with two secondary amine N atoms and twoCl- occupying sites at the base of a distorted square pyramid capped by the tertiaryamine N atom. The pair of Cl' attached to the two Cu(Ⅱ) are held in anti configuration. |
