In the crystal structure of the title compound, [ZnCl(2)(C(14)H(12)N(2)O(2))], the Zn(II) center is four-coordinated by two N atoms from one 2,9-dimeth-oxy-1,10-phenanthroline ligand and two Cl atoms. The coordination geometry is distorted tetra-hedral, as the Zn-N bond distances are shorter than the Zn-Cl distances, and the Cl-Zn-N and Cl-Zn-Cl bond angles are much larger than the N-Zn-N angle. For the ligand, the O and C atoms of the meth-oxy groups are almost in the plane defined by the phenanthroline ring. The two O atoms deviate from the phenanthroline mean plane by 0.076 (2) and 0.084 (2) Å, and the two methyl C atoms deviate from the phenanthroline mean plane by 0.035 (3) and 0.361 (3) Å. There are medium π-π stacking interactions between two parallel phenanthroline rings with a centroid-centroid distance of 3.7860 (2) Å and a dihedral angle between the plane defined by the two parallel phenanthroline rings of 1.13 (5)°.
在标题化合物[ZnCl₂(C₁₄H₁₂N₂O₂)]的晶体结构中,Zn(II)中心由来自一个2,9 - 二甲氧基 - 1,10 - 菲咯啉配体的两个N原子和两个Cl原子进行四配位。配位几何形状为扭曲的四面体,因为Zn - N键长比Zn - Cl键长短,且Cl - Zn - N和Cl - Zn - Cl键角比N - Zn - N角大得多。对于配体,甲氧基的O和C原子几乎处于由菲咯啉环所定义的平面内。两个O原子偏离菲咯啉平均平面的距离分别为0.076(2) Å和0.084(2) Å,两个甲基C原子偏离菲咯啉平均平面的距离分别为0.035(3) Å和0.361(3) Å。在两个平行的菲咯啉环之间存在中等强度的π - π堆积相互作用,质心 - 质心距离为3.7860(2) Å,两个平行菲咯啉环所定义平面之间的二面角为1.13(5)°。
