Noncyclometalated and cyclometalated Pt(II) complexes with azo- or imine-based ligands were synthesized and structurally characterized. These Pt(II) complexes had square-planar structures, with cyclometalation resulting in six-membered ring formation and highly distorted square-planar geometry. The Pt(II) complex with an azo-based ligand easily underwent cyclometalation, even at room temperature, while the Pt(II) complex with an imine-based ligand required a higher reaction temperature and a solvent with higher solubility. Cyclometalation in these complexes was also dependent on the presence of water as reaction solvent. Water as an additive was considered to eliminate HCl originating from the phenyl ring and coordinate chloride ions, promoting cyclometalation.

合成了基于偶氮或亚胺基配体的非环金属化和环金属化的Pt（II）配合物，并对其结构进行了表征。这些Pt（II）配合物具有正方形平面结构，具有环金属化作用，导致六元环形成和高度扭曲的正方形平面几何形状。具有偶氮基配体的Pt（II）配合物即使在室温下也容易进行环金属化，而具有亚胺基配体的Pt（II）配合物则需要更高的反应温度和更高溶解度的溶剂。这些络合物中的环金属化也取决于水作为反应溶剂的存在。认为水作为添加剂可消除源自苯环的HCl和配位氯离子，从而促进环金属化。
