Abstract: The metal cluster can be controlled by adjusting the size of the anionic templates and by using different peripheral organic ligands. In this paper, we employ RC≡CAg (R = 4-tBu-Ph, Ph, tBu), CF3SO3Ag, NH4X (X = Br, VO3) acting as starting materials to obtain four silver ethynide complexes incorporating the sulfonate ligands, namely, [Ag3(4-tBu-PhC≡C)2(CF3SO3)]n (1), {[Br@Ag15(PhC≡C)10(CF3SO3)4][Ag4(PhC≡C)4][Br@Ag15(PhC≡C)10(CF3SO3)4]}n (2), [Br@Ag15(tBuC≡C)10(CF3SO3)4]n (3) and [V2O7@Ag24(tBuC≡C)14(CF3SO3)6] (4). Single-crystal X-ray analysis revealed that complexes 1-3 display different coordination chain structures, while 4 contain high-nuclearity silver(I) composite clusters enclosing a [V2O7]4- template ion, that are supported by CF3SO3- ligands.
摘要：可以通过调节阴离子模板的大小和使用不同的外围有机配体来控制金属簇。在本文中，我们使用RC≡CAg (R = 4-tBu-Ph, Ph, tBu), CF3SO3Ag, NH4X (X = Br, VO3)作为起始材料，获得四种包含磺酸配体的乙炔银配合物，即[Ag3(4-tBu-PhC≡C)2(CF3SO3)]n (1), {[Br@Ag15(PhC≡C)10(CF3SO3)4][Ag4(PhC≡C)4][Br@Ag15(PhC≡C)10(CF3SO3)4]}n (2), [Br@Ag15(tBuC≡C)10(CF3SO3)4]n (3)和[V2O7@Ag24(tBuC≡C)14(CF3SO3)6] (4)。单晶X射线分析显示，配合物1-3显示出不同的配位链结构，而4含有高核银（I）复合团簇，包围[V2O7]4-模板离子，由CF3SO3-配体支撑。
