Abstract

Four Zinc(II) coordination polymers based on a new ligand with terpyridyl and benzenesulfonyl groups, namely, [Zn_1.5(STP)₂Cl]_n·1.5nH₂O (1), [Zn(STP)(1,4- bdc)_0.5]_n·0.5nH₂O (2), [Zn(STP-O)]_n·0.5nH₂O (3), [Zn(STP-OH)(1,4-bdc)_0.5]_n·0.5nH₂O (4), (HSTP = 2-(4,2':6',4″-terpyridine-4'-yl)benzenesulfonic acid) have been synthesized under hydrothermal and characterized by elemental analysis, IR, PXRD and single crystal X-ray diffraction. Compound 1 exhibits an interpenetrating 3D network. Compound 2 displays a (3,4)-connected Ins topological network. Compound 3 shows a (3,6)-connected 3D rtl network. Compound 4 reveals a (3,4)-connected Ins topological network. The structural diversities well confirm the rich coordination chemistry of HSTP. The photoluminescence for 1–2 and thermal stabilities of 1–4 were also studies. Additionally, a brief analysis for hydroxylation of terpyridine group during hydrothermal reaction was carried out.

含有新型 "官能化 "萜吡啶基磺酸盐配体的锌配位聚合物的合成、晶体结构和发光特性

四种基于具有叔吡啶基和苯磺酰基的新配体的锌(II)配位聚合物，即[Zn1.5(STP)2Cl]n-1.5nH2O (1)、[Zn(STP)(1,4- bdc)0.5]n-0.5nH2O (2)、[Zn(STP-O)]n-0.5nH2O (3)、[Zn(STP-OH)(1,4- bdc)0.5]n-0.5nH2O (4)，（HSTP = 2-(4,2':6',4″-叔吡啶-4'-基)苯磺酸）的水热合成，并通过元素分析、红外光谱、PXRD 和单晶 X 射线衍射进行了表征。化合物 1 呈现出相互渗透的三维网络。化合物 2 显示了一个 (3,4) 连接的 Ins 拓扑网络。化合物 3 显示了一个 (3,6) 连接的三维 rtl 网络。化合物 4 揭示了一个 (3,4) 连接的 Ins 拓扑网络。结构的多样性很好地证实了 HSTP 丰富的配位化学性质。此外，还对 1-2 的光致发光和 1-4 的热稳定性进行了研究。此外，还对水热反应过程中terpyridine 基团的羟基化进行了简要分析。

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
