Two novel homochiral lanthanide-silver heterometallic coordination polymers LnAg(OAc)(IN)3 [Ln = Nd (1), Eu (2), HIN = isonicotinic acid, HOAc = acetic acid] have been prepared under hydrothermal conditions, which were characterized by elemental analysis, infrared, thermogravimetric analysis, and single-crystal X-ray diffraction. Both complexes are isostructural and crystallize in a hexagonal system, chiral space group P6(1)22. Both polymers are constructed from infinite right-handed homochiral helical chains with Ln-O-Ag connectivity, representing the first examples of homochiral lanthanide-transition metal heterometallic coordination polymers with a 3D coordination framework based on spontaneous resolution. Furthermore, the luminescent properties of 2 were studied.
在水热条件下制备了两种新型的同手性镧系-银异金属配位聚合物LnAg(OAc)(IN)₃[Ln = Nd (1)，Eu (2)，HIN = 异烟酸，HOAc = 乙酸]，通过元素分析、红外光谱、热重分析和单晶X射线衍射对其进行了表征。两种配合物具有相同的结构，结晶于六方晶系，手性空间群为P6(1)22。两种聚合物均由具有Ln-O-Ag连接性的无限右手同手性螺旋链构成，是基于自发拆分的具有三维配位框架的同手性镧系-过渡金属异金属配位聚合物的首例。此外，还研究了2的发光性质。
