Abstract Isomers play a crucial role in the formation of coordination architectures. Herein we report two Sr(II) coordination compounds, mononuclear [Sr(2-pytzipa)2(H2O)4] (1) and 1D [Sr(3-pytzipa)2(H2O)2]n (2) derived from two isomers, 5-(n-pyridyl)tetrazole-2-isopropionic acid (Hn-pytzipa, n = 2, 3). Furthermore, differential scanning calorimetry and thermogravimetric-differential thermogravimetric analyses were applied to evaluate the thermal decomposition behavior of such compounds. The relevant thermodynamic parameters (ΔH, ΔS, and ΔG) of the decomposition process of 1 and 2 were calculated as well. Graphical Abstract

两种衍生自异构 5-(n-pyridyl)tetrazole-2-isopropionic acid (n = 2, 3) 的 Sr(II) 化合物的合成和热行为

摘要 异构体在配位结构的形成中起着至关重要的作用。在本文中，我们报告了两种 Sr(II) 配位化合物，单核 [Sr(2-pytzipa)2(H2O)4] (1) 和一维 [Sr(3-pytzipa)2(H2O)2]n (2)，来自两个异构体，5-(n-pyridyl)tetrazole-2-isopropionic 酸 (Hn-pytzipa, n = 2, 3)。此外，差示扫描量热法和热重-差示热重分析被应用于评估此类化合物的热分解行为。还计算了1和2分解过程的相关热力学参数(ΔH、ΔS和ΔG)。图形概要
