Reactivity of azido terpyridine Pd(ii) and Pt(ii) complexes towards 4,4,4-trifluoro-2-butynoic acid: structural insight into the triazolato coordination mode.

ABSTRACT: The mono- and binuclear azido terpyridine square-planar complexes of ionic formulas, [Pd₂(N₃)₂L]²⁺ and [Pt(N₃)L]⁺ (L = 1,4-bis(2,2':6',2''-terpyridin-4'yl)benzene), underwent the catalyst-free [3 + 2] cycloaddition coupling with 4,4,4-trifluoro-2-butynoic acid at ambient temperature affording the corresponding triazolate complexes. A mixture of triazolate isomers was generated by these inorganic click reactions. An increase in the solubility of the compounds was achieved by replacing the azido ligand with a triazolato ligand. By calculating the vibrational modes and comparing the total electronic and zero-point energy values, the local minimum structures of the complexes and the nature of the predominant triazolate isomer we
