“…For instance, Santi has reported the synthesis and mixed valence properties in ferrocenyl-based bimetallic complexes [10][11][12][13]. Wang has reported the synthesis and crystal structure of ferrocene-bridged indenyl carbonyl complexes of iron, ruthenium and molybdenum [14]. Gaede [15] has reported crystal structures of ferrocene-substituted indenyl complexes [16][17][18][19][20][21][22].…”

In this study, four ferrocenyl indenyl derivatives, C 9 H 7 -CC-Fc (1), C 9 H 7 -CC-Ph-Fc (2), C 9 H 7 -CC-Ph-CC-Fc (3), and C 9 H 7 -Ph-CC-Fc (4) (where C 9 H 7 ¼indenyl; Fc¼C 5 H 5 FeC 5 H 4 ; Ph¼C 6 H 5 ), have been synthesized by Sonogashira and Suzuki cross-coupling reactions and characterized by elemental analysis, and FT-IR, 1 H, 13 C-NMR, and MS spectroscopic methods, respectively. The molecular structures of 1, 2, and 4 were determined by X-ray single crystal diffraction. Two molecules appeared in the crystal structure of 4, and they interact through an intermolecular hydrogen bond. The electrochemical redox potential differences in 1-4 were investigated using cyclic voltammetry and calculations.

Reactions of the pyridyl side chain functionalized indenes 3‐R‐C9H7 [R = (C5H4N)CH2CMe2 (1), (MeC5H3N)CH2CMe2 (2), (C5H4N)CH2 (6)] with Ru3(CO)12 in refluxing xylene gave the facial coordinated indenyl cluster [μ3‐η5:η2:η2‐(C5H3N)CH2Me2C(C9H6)]Ru4(μ3‐CO)(CO)7 (8), the syn‐η5:η6‐coordinated indenyl cluster [μ‐η5:η6‐(MeC5H3N)CH2CMe2(C9H6)Ru2(CO)3]2 (10), and the η1:η2‐coordinated indenyl complex[η2‐(C5H3N)CH2(C9H7)][η1:η2‐(C5H4N)CH2(C9H6)]Ru2(CO)4(18), respectively, in addition to the normal diruthenium complexes [(η5‐RC9H6)Ru(CO)]2(μ‐CO)2 [R = (C5H4N)CH2CMe2 (7), (MeC5H3N)CH2CMe2 (9), (C5H4N)CH2 (17)]. When the pyridyl side chains were replaced by other bulky groups [R = tBu (3), PhCH2Me2C (4), (C9H6N)CH2Me2C (5)], the similar syn‐η5:η6‐coordinated indenyl clusters 12, 14, and 16 were also obtained. When 1 or 2 were treated with Ru3(CO)12 in refluxing heptane, the ionic clusters {[(C5H4N)CH2Me2C(C9H6)]Ru(CO)2}+[HRu6(CO)18]– (19), [(C5H4N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (20), and complex 8 or ionic clusters {[(MeC5H3N)CH2Me2C(C9H6)]Ru(CO)2}+[HRu6(CO)18]– (21) and [(MeC5H3N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (22) were obtained. Similar treatment of 5 or 6 with Ru3(CO)12 in refluxing heptane gave the ionic clusters [(C9H6N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (23) or {[η3‐(C5H4N)CH(C9H7)][η2‐(C5H4N)CH2(C9H7)]Ru(CO)}+[HRu6(CO)18]– (24), respectively, in addition to complex 18 in the latter case. The molecular structures of 8, 9, 10, 14, 17, 18, 21, 22, and 24 were determined by X‐ray diffraction analysis.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
