用C-13和P-31 CP/MAS NMR研究了（1，3-丁二烯）M（R_2PC_2H_4PR_2）化合物（M = Ni，Pd，Pt; R = Pr（i），Bu（t），Cy）的固态结构。 二烯采用的键合模式取决于金属的性质：钯化合物含有η-2-二烯分子，其中R为环己基的镍化合物含有η-4-二烯分子，而Pr（i）2 PC 2 H4 PPr（i）2稳定的铂化合物含有铂环戊烯环。 用X射线衍射法测定了（eta-2- 1，3-C4 H6）Pd（Cy 2 PC 2 H4 PCy 2）和（eta-4- 1，3-C4 H6）Ni（Cy 2 PC 2 H4 PCy 2）的晶体结构。
The structure of the (1,3-butadiene)M(R2PC2H4PR2) compounds (M = Ni, Pd, Pt; R = Pr(i), Bu(t), Cy) in the solid-state have been investigated by C-13 and P-31 CP/MAS NMR spectroscopy. The bonding mode adopted by the diene is dependent upon the nature of the metal: the palladium compounds contain an eta-2-diene molecule, the nickel compound where R is cyclohexyl contains an eta-4-diene molecule whereas the Pr(i)2PC2H4PPr(i)2-stabilized platinum compound contains a platinacyclopentene ring. The crystal structures of (eta-2-1,3-C4H6)Pd(Cy2PC2H4PCy2) and (eta-4-1,3-C4H6)Ni(Cy2PC2H4PCy2) have been confirmed by X-ray diffraction.
