The acetate anions show different types of coordination mode: one acts as a bridge by coordination of the same oxygen atom with Pb(II) ions and the other as a monodentate coordination by one of the oxygen atoms with Pb(2).

📌 3 Key Takeaways

🎯
Objective & Hypothesis:A novel [Pb2(m-atrz)2(m-CH3COO)(CH3COO)]n (atrz = 3-amino-1,2,4-triazole) complex was synthesized and characterized by IR spectroscopy, thermogravimetric analysis, and single crystal X-ray diffraction.
📊
Key Findings & Data:The molecular structure shows that the complex is a coordination polymer in which there are 2 different lead(II) ions with coordination number of 5, Pb(2), and, with a coordination number of 4, Pb(1).
💡
Conclusion & Impact:The acetate anions show different types of coordination mode: one acts as a bridge by coordination of the same oxygen atom with Pb(II) ions and the other as a monodentate coordination by one of the oxygen atoms with Pb(2).

Abstract

A novel [Pb2(m-atrz)2(m-CH3COO)(CH3COO)]n (atrz = 3-amino-1,2,4-triazole) complex was synthesized and characterized by IR spectroscopy, thermogravimetric analysis, and single crystal X-ray diffraction. The molecular structure shows that the complex is a coordination polymer in which there are 2 different lead(II) ions with coordination number of 5, Pb(2), and, with a coordination number of 4, Pb(1). Each atrz acts as a bridging ligand between 2 Pb(II) ions through the 2 adjacent nitrogen atoms of the triazole ring. The acetate anions show different types of coordination mode: one acts as a bridge by coordination of the same oxygen atom with Pb(II) ions and the other as a monodentate coordination by one of the oxygen atoms with Pb(2).

  1. Experimental General procedures 3-Amino-1,2,4-triazole and lead(II) acetate trihydrate were purchased from Sigma-Aldrich Co.; sodium nitrite was purchased from Carlo Erba. All chemicals and reagents were used as received without any purification. IR spectra were recorded as KBr pellets using a PerkinElmer LR 64912C in the frequency range 4000−400 cm −1 Thermogravimetric analysis was performed on a PerkinElmer Diamond TG/DTA by heating the sample at a rate of 20 ◦ C/min under flowing nitrogen. Melting point was measured on an Electrothermal 9100 apparatus and was uncorrected. X-ray crystallography Preparation of [Pb2( µ -atrz)2( µ -CH3COO)(CH3COO)]n ) selected bands: 443 vs, 470 m, 665 vs, 837 s, 1064 s, 1177 m, 1268 s, 1434 vs, 1497 ms, 1526 s, 1549 ms, 1627 vs, 2955 w, 3137 w, 3186 w, 3294 w, 3356 s.
