摘要
The title cluster compound-Cu5(BTA)6(TT-A)4·5DMF was prepared using thenyltrifluoroacetone and benzotriazolate ligands. The crystal structure indicates that a tetrahedral array of Cu(l), Cu(2), Cu(3) and Cu(4) ions surrounding a central Cu(5) ion are held together by bridging tridentate BTA- and terminated by TTA- bond cap. The three nitrogen atoms of a BTA- bond three different copper ions to form a η3-benzotriazolate. The central Cu ion has a distorted octahedral structure and the surrounding Cu ions are 5 coordinated forming distorted tetragonal structures. The distances between the surrounding Cu(Ⅱ) ions and the central Cu(Ⅱ) ion are in the range of 0.3561-0.3755 nm and those between the surrounding Cu(Ⅱ) ions are in the range of 0.5785-0.6301nm.
