(Ferrocenylacyl)germanes, (η5-C5H5)Fe(η5-C5H4)COGeR3 (R3 = Me3 (I), Ph3 (II)) have been synthesized and their physical and structural properties investigated, both spectroscopically and via single crystal X-ray analysis. Basicity measurements, via H-bonding to phenol, indicate that I and II are less basic than their silicon analogs, a feature corroborated by infrared and structural analysis. Thus,
(Ferrocenylacyl)锗,(η 5 -C 5 H ^ 5)的Fe(η 5 -C 5 H ^ 4)COGeR 3(R 3 =我3(I)中,Ph 3(II))已被合成和它们的物理和结构光谱和通过单晶X射线分析研究了其性质。通过与苯酚的氢键进行的碱度测量表明,I和II的碱度低于其硅类似物,这一特征已通过红外和结构分析得到证实。因此,I和II在1594和1596 cm -1的v(C = O)频率约为18 cm -1 比相应的酰基硅烷高,而CO键长为1.223Å,比硅类似物1.231Å要短。
