Coordination and organometallic chemistry of metal-NO complexes.

Publisher Summary This chapter surveys the rapidly growing field comprising the chemistry of transition metal complexes containing ligands which are made up only of carbon atoms within their coordination spheres. The chapter describes metal complexes which contain linear or cyclic ligands of composition C n (n n ligands, in order of increasing carbon content of the ligand have been discussed. This is followed by a discussion on complexes of cyclic all-carbon ligands, such as [C 3 {Fe(CO) 2 Cp} 3 ] + . Complexes containing C n ligands associated with binuclear metal–metal bonded systems are followed by an account of metal cluster complexes containing C n ligands. It also includes hybrid complexes where a cluster supports a C n ligand also attached to a mononuclear metal–ligand fragment. The study is broadly based on a group-by-group approach and includes salient details of synthesis, properties, chemistry and electronic structure.

Ligating ability of 1,1′-bis(diphenylphosphino)ferrocene: a structural survey (1994–1998)

Group 10 metal compounds of 1,1′-bis(diphenylphosphino)ferrocene (dppf) and 1,1′-bis(diphenylphosphino)ruthenocene: a structural and electrochemical investigation. X-ray structures of [MCl2(dppr)] (M=Ni, Pd)

Reaction of [Fe3(CO)12] with bidentate phosphines: Redox behavior of products

Reaction of [Os3(CO)10(MeCN)2] with 2,3-bis(2-pyridyl)pyrazine and pyrazyne. Synthesis, characterization and electrochemical behavior of 1:1 and 1:2 ligand:cluster complexes

The bis(ruthenium)alkyne complex [cis-{RuCl (bpy)2(m-CoC-)}]2 (1) was obtained by treatment of 1 equiv of either 1,4-bis(trimethylsilyl)-1,3-butadiyne or bis(trimetylsilyl)acetylene with 2 equiv of cis-[RuCl2(bpy)2].2H2O, NaF and NaBF4 salts in methanol/CH2Cl2 mixture (10/1) in 52% and 35% yields, respectively. 1H, 13C{H} NMR and principally electrochemical analyses confirmed that the same product was obtained from the two reactions. Cyclic voltammetric analyses of (1) from 0 to 1.20 V displays two one-electron quasi-reversible oxidation peaks attributed to the Ru(II)/Ru(III) couple. The redox processes are separated by 520 mV, indicating a significant electronic communication between the two metallic centers.
