The reaction of 2-(arylazo)pyridines, RH4C6N
NC5H4N (aap, 1 where R=H (pap), p-Me (p-tap), p-Cl (p-Clpap)) with K2PtCl4 in 1:2 boiling acetonitrile–water affords orange–red complexes of the type Pt(aap)Cl2 (2). The IR spectrum shows two ν(Pt
Cl) stretches suggesting cis-PtCl2 configuration. The structural confirmation was carried out by an X-ray diffraction study of Pt(pap)Cl2 (2a). The addition of catechols to a chloroform–methanol solution of Pt(aap)Cl2 in the presence of Et3N yielded green colored mixed-ligand complexes of the formula Pt(aap)(O,O) (O,O
