Two new coordination polymers, namely, [Na₂(μ₄-TBT)(H₂O)₄]_n (1) and [K₂(μ₄-TBT)(H₂O)₄]_n (2) [H₂TBT = tetrabromoterephthalic acid] were synthesized and their crystal structures were characterized via the single-crystal X-ray diffraction technique. In both of them, halogen bond, metallophilic and hydrogen bonding interactions were observed. Compound 1 exhibited the perpendicular 2D → 3D interpenetration of the (4,4) square network to a 3D supramolecular structure. Compound 2 showed weak metal⋯carbon interactions. These two compounds were synthesized via the sonochemical reaction, and their solid-state mechanochemical conversions to each other were investigated with IR spectroscopy as well as PXRD, EDAX, TGA and SEM analyses. Also, the irreversible conversion of 2 to 1 was observed.

钾配位聚合物纳米结构到具有卤素键，金属-碳和金属-金属相互作用的互穿钠配位聚合物的机械化学转化

两个新的配位聚合物，即，[钠₂（μ ₄ -TBT）（H ₂ O）₄ ] _Ñ（1）和[K ₂（μ ₄ -TBT）（H ₂ O）₄ ] _Ñ（2）[H合成了₂ TBT =四溴对苯二甲酸]，并通过单晶X射线衍射技术表征了它们的晶体结构。在它们两者中，均观察到卤素键，嗜金属键和氢键相互作用。化合物1展示了（4,4）正方形网络与3D超分子结构的垂直2D→3D互穿。化合物2表现出弱的金属碳相互作用。这两种化合物是通过声化学反应合成的，并通过红外光谱以及PXRD，EDAX，TGA和SEM分析研究了它们之间的固态机械化学转化率。另外，观察到2至1的不可逆转化。
