ABSTRACT Coordinatively unsaturated dithiophosphato complex [Cd((MeO)2PS2)2] (1) was reacted with the bifunctional ligands 3,5-di-(4-pyridyl)-1,2,4-thiadiazole (L1) and 3,5-di-(3-pyridyl)-1,2,4-thiadiazole (L2) to give the helicoidal coordination polymer (1·L1)∞ and the paddle-wheel dimer (1·L2)2, both characterised by single-crystal X-ray diffraction. A comparison of the structures with the different supramolecular constructs obtained by reacting L1 and L2 with differently P-substituted dithiophosphoric NiII complexes allowed to evaluate the role of the metal ion for the predictable assembly of this class of coordination polymers. Graphical abstract Cadmium dithiophosphato complex [Cd((MeO)2PS2)2] (1) was reacted with bis-functional dipyridyl-thiadiazole ligands L1 and L2 to give the helicoidal coordination polymer (1·L1)∞ and the discrete dimeric paddle-wheel (1·L2)2. A comparison of the structures with different supramolecular constructs previously obtained is presented.

摘要 配位不饱和二硫代磷酸络合物 [Cd((MeO)2PS2)2] (1) 与双功能配体 3,5-二-(4-吡啶基)-1,2,4-噻二唑 (L1) 和 3,5 -di-(3-pyridyl)-1,2,4-噻二唑 (L2) 得到螺旋配位聚合物 (1·L1)∞ 和桨轮二聚体 (1·L2)2，两者均以单晶为特征X射线衍射。通过将 L1 和 L2 与不同的 P 取代的二硫代磷酸 NiIII 复合物反应获得的不同超分子结构的结构比较，可以评估金属离子对此类配位聚合物的可预测组装的作用。图形摘要二硫代磷酸镉络合物 [Cd((MeO)2PS2)2] (1) 与双功能双吡啶基-噻二唑配体 L1 和 L2 反应，得到螺旋配位聚合物 (1·L1)∞ 和离散的二聚桨轮(1·L2)2。呈现了与先前获得的不同超分子构建体的结构的比较。
