In the presence of HCl, the reaction of 2-chloroaniline, methyl anthranilate and sodium nitrite formed 1-[(2-chloro)benzene]-3-[(2-carboxymethyl)benzene]triazene (HL). In the presence of triethylamine (Et3N), the reaction of HL and [Pd(CH3CN)(2)]Cl-2 gave a new dinuclear triazenido complex, [Pd-2(1)(L)(2)] with metal-metal bond, which has been characterized by physico-chemical and spectroscopic methods. The irradiation by a 100-W high-pressure mercury lamp led to a cleavage of the Pd-Pd bond in [Pd-2(1)(L)(2)]. Electrochemical studies showed that [Pd-2(1)(L)(2)] can electro-catalyze hydrogen evolution both from acetic acid and water. Spectroscopic investigations indicated that the introduction of palladium ion leads the strength of photoluminescence of HL to a significant decrease. (C) 2019 Elsevier Ltd. All rights reserved.
