摘要 ZnCl2, PhONa和Et4NCl稨2O在乙腈溶剂中反应合成了一种二核锌配合物[Et4N]2[Zn2(OPh)2Cl4]。X射线衍射结果表明,晶体属单斜晶系,C2/m空间群,晶胞参数 a = 14.1366(2), b=13.6985(5), c=9.3308(3)牛?107.851(2)o, V=1719.92(9)?,C28H50O2N2Zn2Cl4,Mr=721.24,Z=2,Dx=1.393g/cm3,μ(MoKα)=1.732mm—1,F(000)=756, R=0.0552, wR=0.1534, S=1.027。 配合物是由2个阳离子Et4N+和1个阴离子[Zn2(OPh)2Cl4]2—组成。阴离子[Zn2(OPh)2Cl4]2—包含着1个中心Zn2O2菱形平面。配合物中的2个锌原子通过2个苯酚中的氧原子桥连,每个锌原子还与2个氯原子配位形成变形四面体结构。 The reaction of zinc chloride with sodium phenoxide followed by the addition of tetraethylammonium chloride monohydrate gave a dimer zinc complex, [Et4N](2)[Zn-2(OPh)(2)Cl-4]. The crystal structure of it has been determined. It crystallizes in monoclinic space group C2/m with a = 14.1366(2), b = 13.6985(5), c = 9.3308(3)Angstrom, beta = 107.851(2)degrees, V = 1719.92(9)Angstrom (3), C28H50O2N2Zn2Cl4, M-r = 721.24, Z = 2, D-x = 1.393 g/cm(3), mu (MoK alpha) = 1.732 mm(-1), F(000) = 756, R = 0.0552, wR = 0.1534, S = 1.027. The complex consists of an anion of [Zn-2(OPh)(2)Cl-4](2-) and two cations of Et4N+. The anion [Zn-2(OPh)(2)Cl-4](2-) contains a central Zn(2)O(2)rhombic plane. The two zinc atoms are doubly bridged by two oxygen atoms of phenolate ligands and each zinc atom coordinates to two chlorine ligands to form a tetrahedral coordination.
