Heterobimetallic compounds [Ru(g 5 -Cp)(dppf)X] (X 5 Cl, Br, I and N 3 ): synthesis, electrochemical analysis, and the crystal structure of [Ru(g 5 -Cp)(dppf)I] [dppf 5 1,1 0 -bis- (3) and [Ru(g 5 -Cp)(dppf)N 3 ] (4) were obtained by reactions of [Ru(g 5 -Cp)(PPh 3 ) 2 Cl] with 1,1 0 -bis(diphenylphosphino) ferrocene (dppf) and characterized by IR, NMR ( 1 H, 13 C and 31 P), 57 Fe Mössbauer spectroscopy and cyclic voltammetry. Additionally, the compound (3) was structurally characterized by X-ray crystallography, and the results were as follows: orthorhombic, Pbca, a = 18.2458 (10), b = 20.9192(11), c = 34.4138(19) Å , a = b = c = 90°, V = 13135.3(12) Å 3 and Z = 16.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
