A new series of mixed chelates of nickel(II), Ni(diam) (β-dik)X·nH2O (X= halide or pseudohalide anion, n=0–2), was prepared, and their structures in solid state and in various organic solvents were studied. Most of the chelates were octahedral, many of them being obtained as mono- or dihydrates. When the solid chelates were heated at reduced pressure, the main reactions were dimerization (X=pseudohalide)
制备了一系列新的镍 (II)、Ni(diam) (β-dik)X·nH2O(X= 卤化物或拟卤化物阴离子,n=0-2)的混合螯合物,以及它们的固态和固态结构。研究了各种有机溶剂。大多数螯合物是八面体的,其中许多是作为一水合物或二水合物获得的。当固体螯合物在减压下加热时,主要反应是二聚(X=伪卤化物)、脱水(X=I)和歧化(X=Br或Cl)。另一方面,螯合物在有机溶剂中表现出复杂的结构变化,其中一些在固体中没有观察到,这取决于 X 的性质和溶剂的极性特征。
