In the title complex, [Cd(NCS)(2)(C(22)H(20)N(6))], the Cd(II) ion is in a CdN(6) coordination geometry which is inter-mediate between octa-hedral and trigonal-prismatic. The dihedral angles formed between the mean planes of the pyrazole rings and the phenanthroline system are 15.74 (15) and 16.30 (13)°. In the crystal, there is a π-π stacking inter-action involving two symmetry-related pyrazole rings, with a centroid-centroid distance of 3.664 (3) Å. In addition, there is a relatively short inter-molecular contact between C atoms [C⋯C = 3.399 (6) Å] involving symmetry-related pyridine rings along the a axis.
在标题配合物[Cd(NCS)₂(C₂₂H₂₀N₆)]中,Cd(II)离子处于CdN₆配位几何构型,介于八面体和三角棱柱体之间。吡唑环的平均平面与菲咯啉体系之间形成的二面角为15.74 (15)°和16.30 (13)°。在晶体中,存在涉及两个对称相关吡唑环的π-π堆积相互作用,质心间距为3.664 (3) Å。此外,沿着a轴存在涉及对称相关吡啶环的C原子间相对较短的分子间接触[C⋯C = 3.399 (6) Å]。
