(η ⁵ ‐Pentamethylcyclopentadienyl)Cobalt complexes

Molecular and Crystal Structures of Cp*M(S2N2) (M = Co, Rh, Ir) and Related Compounds

“…Solvents were dried, purified and stored according to common procedures. [26] [27] [S 4 N 3 ]Cl, [28] Cp*Co(CO) 2 , [29] [Cp*RhCl 2 ] 2 , [30] [Cp*IrCl 2 ] 2 , [30] [nBu 2 Sn(S 2 N 2 )] 2 [6] and 2 [4] were prepared according to published methods. Compound 6 was prepared by the published procedure but the reactants were mixed in their CH 2 Cl 2 solutions.…”

Reactions of half-sandwich Co(III) complexes with heterocyclic thione ligands: η2-N, S coordination mode and formation of S–S bond

“…Solvents were dried and deoxygenated by M. Braun Solvent Purification System (4464) and collected just before use. Cp * Co(CO)I 2 [39], CpCo(CO)I 2 [39] and 4-HS-C 6 H 4 -N@CH-4'-C 5 H 4 N(HL) [40] were prepared according to the procedures described in the literature. 4-Mercaptopyridine, 2-mercaptobenzothiazole, 2-mercaptobenzoxazole and 2-mercaptothiazoline were used as purchased without further purifications.…”

Syntheses and properties of NCN-bridged tri- and tetranuclear complexes of cobalt and rhodium

“…[Cp * CoI 2 ] 2 (1b) [5], [Cp * RhCl 2 ] 2 (1c) [6], [Cp * CoCl] 2 (7) [7], and NaNCNH [8] were prepared according to the literature methods. Solvents were dried by common procedures and degassed before use.…”

“…Although cyanamide anions (NCN 2À and NCNH À ) are among such molecules to be expected to work as unique bridging ligands for the construction of polynuclear systems owing to their soft, sterically small, and potentially polydentate nature, transition metal complexes with or NCNHbridges [3] have poorly been explored. Recently we have shown that the diiridium(III) complex [Cp * IrCl 2 ] 2 (1a, Cp * = g 5 -C 5 Me 5 ) reacts with NaNCNH or Na 2 NCN to afford the 16-membered macrocyclic NCNH-bridged tetrairidium complex [Cp * IrCl(l 2 -NCNH-N,N 0 )] 4 (2a) or the NCN-bridged diiridium complex [Cp * Ir(l 2 -NCN-N,N)] 2 (3), respectively, which can further be converted into the C 3 -elongated cubane-like NCN-bridged tetrairidium complex [Cp * Ir(l 3 -NCN-N,N,N 0 ) 3 (IrCp * ) 3 (l 3 -NCN-N,N,N)] (4a), the regular cubane-type NCN-bridged tetrairidium complex [Cp * Ir(l 3 -NCN-N,N,N)] 4 (5) and the heterotrinuclear complexes [(Cp * Ir) 2 (ML)(l 3 -NCN-N,N,N) 2 ] + (ML = RuCp, Rh(cod), Pd(g 3 -C 3 H 5 ); Cp = g 5 -C 5 H 5 ; cod = cycloocta-1,5-diene) (Scheme 1) [4]. In this study, we have synthesized cobalt and rhodium analogues of the 16-membered macrocyclic and C 3 -elongated cubane-like complexes, …”
