-[Cu(cyan-κO2)2(NH3)4] (6), trans-[Ni(cyan-κN)2(NH3)4] (7), (OC-6-33)-[Ni(cyan-κN)2(NH3)2(H2O)2] (8), and [Cu(cyan-κN)(PPh3)2]·2CDCl3 (9). The results are discussed together with the previously reported structures of the other three complexes, [M(cyan-κN)(H2O)5](cyan)·2H2O (M = Mn (2), Co (3), Ni (4)). In all cases, the ribbon of cyanurates is propagated through a recognition interaction involving
描述了一系列九种配位化合物,其中一个常见的超分子结构,氰尿酸盐带,在金属中心、配位几何、配位环境和晶体类型的变化中持续存在。通过单晶 X 射线衍射测定的合成和固态结构描述了六种配合物,反式-[Cu(cyan-κN)2(H2O)2]·2Na(cyan)·4H2O ( 1), 反式-[Cu(cyan-κN)2(NH3)2] (5), 反式-[Cu(cyan-κN)2(NH3)2]trans-[Cu(cyan-κO2)2(NH3) 4] (6), trans-[Ni(cyan-κN)2(NH3)4] (7), (OC-6-33)-[Ni(cyan-κN)2(NH3)2(H2O)2] (8) 和 [Cu(cyan-κN)(PPh3)2]·2CDCl3 (9)。结果与之前报道的其他三种配合物 [M(cyan-κN)(H2O)5](cyan)·2H2O (M = Mn (2), Co (3), Ni (4)
