Analytical and Mössbauer spectral data show that Ph2PCH2CH2PPh2(dppe) forms adducts [FeCl2(dppe)] and [FeI2(dppe)], and that [FeCl2(dppe)2] does not exist. The phosphine 1,2-C6H4(PPh2)2(opdp) forms adducts FeX2(opdp)2, which exists in one form (high-spin, trans octahedral) for X = Cl, and in two isomeric forms for X = Br or I. One isomer for X = I is high-spin, trans octahedral, and the other is ionic
分析和Mössbauer光谱数据表明,Ph 2 PCH 2 CH 2 PPh 2(dppe)形成加合物[FeCl 2(dppe)]和[FeI 2(dppe)],并且不存在[FeCl 2(dppe)2 ]。膦1,2-C 6 H 4(PPh 2)2(opdp)形成加合物FeX 2(opdp)2,对于X = Cl,它以一种形式(高旋转,反八面体)存在,并且以两种异构体形式存在。对于X = Br或I。对于X = I的一个异构体是高自旋,反式八面体,另一个是离子低旋和五坐标。将这些结构及其Mössbauer光谱与Me 2 PCH 2 CH 2 PMe 2,Et 2 PCH 2 CH 2 PEt 2,Pr i 2 PCH 2 CH 2 Pr i 2和Ph 2 PCH的衍生物进行了比较。2 PPh 2。
