smaller anions BF4− and PF6−, resulting in the loss of crystallinity. Single crystal X-ray diffraction studies of the new complexes [RuH(dppe)2]BPh4 and trans-[Ru(H2)H(dppe)2]BArF4 are reported. A comparison of the crystal structures of square pyramidal [RuH(dppe)2]BPh4 and octahedral [Ru(H2)H(dppe)2]BPh4 shows that only minor structural changes occur upon loss of H2 from the crystal.
摘要利用31P CP / MAS NMR光谱和单晶X射线衍射研究了固态中反式[Ru(H2)H(dppe)2] +阳离子(dppe = PPh2CH2CH2PPh2)中二氢
配体的损失。虽然在室温下从带有较大抗衡离子BPh4-和B(ArF)4-的晶体样品中观察到容易产生的二氢损失,但ArF = 3,5-
C6H3(
CF3)2,但仅在由较小阴离子
BF4的配合物加热时才发生-和PF6-,导致结晶度的损失。报道了新络合物[RuH(dppe)2] BPh4和反式-[Ru(H2)H(dppe)2] BArF4的单晶X射线衍射研究。方形
金字塔形的[RuH(dppe)2] BPh4和八面体的[Ru(H2)H(dppe)2] BPh4的晶体结构比较表明,从晶体中损失H2后,仅发生了微小的结构变化。
