Abstract:
Three multinuclear Pb II complexes―[Pb 2 (ptptp) 2 (H 2 O) 2 ] ( 1 ), [Pb 2 ( p ‐PDA)(Hptptp) 2 ] ( 2 ), and [Pb 4 ( o ‐PDA) 2 (ptptp) 2 ] · 2H 2 O ( 3 ) [H 2 ptptp = 2‐(5‐{6‐[5‐(pyrazin‐2‐yl)‐1 H ‐1,2,4‐triazol‐3‐yl]pyridin‐2‐yl}‐1 H ‐1,2,4‐triazol‐3‐yl)pyrazine, H 2 PDA = phenylenediacetic acid]―have been synthesized under hydrothermal conditions. Complexes 1 , 2 , and 3 show di‐, di‐, and tetranuclear structures, respectively. The study of the chemical stability of the three complexes demonstrates their remarkable chemical resistance to boiling water and organic solvents. More importantly, complex 1 shows remarkable acid and alkali resistance, which is outstanding among metal–organic solids. The thermogravimetric analysis curve shows that complex 1 possesses high thermal stability (up to 491 °C). Furthermore, the fluorescence of complexes 1 , 2 , and 3 has also been investigated.
