Reactions of metal(II) salts (M = Cd, Ni and Zn) with 5-tert-butylbenzene-1,3-dicarboxylic acid (5-tert-H₂IPA) and N,N′-bis(3-pyridyl)terephthalamide (L¹) or N,N′-bis(4-pyridyl)terephthalamide (L²) afforded {[Cd(L¹)(5-tert-IPA)(H₂O)]·2H₂O}_n, 1, {[Ni(L¹)_1.5(5-tert-IPA)(H₂O)₂]·2.5H₂O}_n, 2, {[Ni(L¹)(5-tert-IPA)(CH₃OH)]·2CH₃OH}_n, 3, [Zn(L¹)_0.5(5-tert-IPA)]_n, 4, and {[Ni(L²)(5-tert-IPA)(H₂O)]·2H₂O}_n, 5, which have been structurally determined by using single-crystal X-ray diffraction. Complexes 1 and 2 are 1D ladders with the {4·8⁴·12}{4}{8}-2,2,4C1 and {8²·12}₂{8}₃-2,2,3C4 topologies, and 3 and 5 are 2D layers showing {8⁴·12²}{8}₂-2,4L2 and {4⁴·6²}-sql topologies, respectively, while complex 4 exhibits a 3-fold interpenetrated 3D net with the {4²·6·10²·12}{4²·6}-coe-3,4-C2/c topology, which can be further simplified as the {6⁵·8}-cds topology, indicating that solvents and metal identity play important roles in determining the structural diversity. Moreover, complexes 2 and 3 display a reversible structural transformation upon coordination as well as co-crystallized solvent exchange between H₂O and CH₃OH, which can be ascribed to the alternations of the bonding modes of the 5-tert-IPA²⁻ ligand upon solvent attack, together with the conformation changes of the L¹ ligand. Their thermal decomposition and the luminescence properties of 1 and 4 are also discussed.

Ni（II）配位聚合物中的结构多样性和修饰：一维阶梯和二维层之间可逆结构转变的特殊现象

金属的反应（II）盐（M =镉，Ni和Zn）与5-叔丁基苯-1,3-二羧酸（5-叔-H ₂ IPA）和Ñ，Ñ ' -双（3-吡啶基）对苯二甲酰胺（L ¹）或N，N'-双（4-吡啶基）对苯二甲酰胺（L ²）得到{[Cd（L ¹）（5-叔-IPA）（H ₂ O）]·2H ₂ O} _n，1，{[Ni（L ¹）_1.5（5-叔-IPA）（H ₂ O）₂ ]·2.5H ₂ O} _n， 2，{[Ni（ L ¹）（5-叔-IPA）（CH ₃ OH）]·2CH ₃ OH} _n， 3，[Zn（ L ¹） _0.5（5 -叔-IPA）] _n， 4和{[Ni（ L ²）（5-叔-IPA）（H ₂ O）]·2H ₂ O} _n， 5，它们已经通过使用单晶结构确定X射线衍射。配合物1和2是具有{4·8 ⁴ ·12} {4} {8} -2,2,4C1和{8 ² ·12} ₂ {8} ₃ -2,2,3C4拓扑的一维阶梯，而3和5是2D层表示{8 ⁴ ·12 ² } {8} ₂ -2,4L2和{4 ⁴ ·6 ² } - SQL拓扑，分别，而复杂的4所呈现3倍穿插3D网与{4 ² ·6 ·10 ² ·12} {4 ² ·6} -coe -3,4- C 2 / c拓扑，可以进一步简化为{6 ⁵·8} -cds拓扑结构，表明溶剂和金属身份在确定结构多样性方面起着重要作用。此外，配合物2和3在配位以及在H ₂ O和CH ₃ OH之间的共结晶溶剂交换时显示出可逆的结构转变，这可以归因于5-叔-IPA ^2-的键合模式的交替。溶剂攻击时的配体，以及L ¹配体的构象变化。还讨论了它们的热分解以及1和4的发光特性。
