摘要： 应用一个简单新方法,在锌粉存在和常温常压下,(Ph2PPy)2NiCl2与CO作用得到新配合物(Ph2PPy)2Ni(CO)2。对后者经X衍射测定了晶体及分子结构,该晶体属正交晶系Pcab+晶胞参数为:a=12.044(3)Å,b=21.322(5)Å,c=24.925(5)Å,Z=8.R=0.051和Rw=0.055,该分子中的镍原子配位为四面体构型。

Abstract: Using a new and simple method, under ordinary temperature and pressure (Ph2PPy)2NiCl2 was reduced by zinc powder in the presence of carbon monoxide to give (Ph2PPy)2Ni(CO)2, the structure of which was determined by X-ray diffraction.The complex crystallizes in the orthogonal space group Pcabwith a=12.044(3)Å, b=21.322(5) Å, c=24.925(5)Åand Z=8.The deviation factors R=0.051 and Rw = 0.055 were obtained for 2166 independent reflections.The nickel atom is of tetrahedral configuration.
