The title compound, [CuCl(2)(C(21)H(19)N(3))], lies on a twofold rotation axis that passes through the N(pyrid-yl)-Cu bond; this symmetry element relates one half of the organic ligand to the other as well as one Cl ligand to the other. The three N atoms span the axial-equatorial-axial sites of the trigonal-bipyramidal coordination polyhedron; the geometry of the Cu(II) atom is 31% distorted from trigonal-bipyramidal (towards square-pyramidal along the Berry pseudorotation pathway).
标题化合物[CuCl₂(C₂₁H₁₉N₃)]位于一个通过N(吡啶基)-Cu键的二重旋转轴上;该对称元素将有机配体的一半与另一半以及一个Cl配体与另一个Cl配体联系起来。三个N原子占据三角双锥配位多面体的轴向-赤道-轴向位置;Cu(II)原子的几何形状相对于三角双锥有31%的畸变(沿着贝里假旋转途径向四方锥畸变)。
