Two new manganese( ii ) and nickel( ii ) bis(hexafluoroacetylacetonate) complexes with N-vinylimidazole were synthesized and characterized by single crystal X-ray diffraction analysis, UV-VIS and IR spectroscopy. Their structures were compared with those of related copper( ii ) and cobalt( ii ) complexes. In the case of copper complex, the coordination site formed by hexafluoroacetylacetonate at the Cu2+ ion and nitrogen atoms of the two vinylimidazole cycles is slightly distorted, while in all the other considered complexes, this distortion is insignificant.

铜（ii），钴（ii），锰（ii）和镍（ii）双（六氟乙酰丙酮）与N-乙烯基咪唑的配合物

合成了两种新的锰（ii）和镍（ii）双（六氟乙酰丙酮）与N-乙烯基咪唑配合物，并通过单晶X射线衍射分析，UV-VIS和IR光谱表征。将它们的结构与相关的铜（ii）和钴（ii）配合物进行了比较。在铜络合物的情况下，由六氟乙酰丙酮酸酯在两个乙烯基咪唑循环的Cu2 +离子和氮原子处形成的配位点略有变形，而在所有其他认为的络合物中，这种变形微不足道。
