2 - acetyldiferrocenylmethane, C5H5FeC5H4CH2C5H3 (COCH3) FeC5H5 ( I ),Mr=426. 1,violet-red prism-like crystal,m. p. 163. 7~166. 3℃,obtained from benzene-ligroin solution (benzene : ligroin=1 : 3). A crystal of approximate dimensions 0. 20×0. 40×0. 45 mm was selected for data collection from a CAD4 diffractometer with graphite monochromated MoKa radiation (λ=0. 71069A). Compound Ⅰ crystallized in the triclinic space group P1 with unit cell dimensions;a = 9. 597(2),b=9. 768 (2),c=11.540(1) A ,α= 111-93(1),β=111. 42(1),γ= 92. 46(2)°,V = 913. 9 A3, Z= 2, and Dc= 1. 548 g/cm3. 3’ - Acetyldiferrocenylmethane, C5H5FeC5H4CH2C5H4FeC5 H4-COCH3(Ⅱ) ,is an isomer of compound Ⅰ ,yellow needle-like crystal,m. p. 110. 5~ 111. 0℃ ,obtained by the same method. A crystal of approximate dimensions 0. 025×0. 01×0. 45 mm was selected for data collection. Compound Ⅱ crystallized in monoclinic space group P21/c with a = 10. 930 (2), b= 5. 907(6) ,c= 27. 729(5) A ,β= 92. 64 (1)°,V=1788. 4A3,Z=4,Dc=1. 583 g/cm3.
