14-Electron Four-Coordinate Ru(II) Carbyl Complexes and Their Five-Coordinate Precursors: Synthesis, Double Agostic Interactions, and Reactivity
The structure of five-coordinate Ru(II) complexes RuHCl(CO)(PPr3)2, 1, RuCl2(CO)(PPr3)2, 2, and Ru(Ph)Cl(CO)(PBu2Me)2, 12, are reported. All three of these complexes have square-based pyramid geometry with the strongest σ-donor ligand trans to the vacant site. These 16-electron complexes do not show bona fide agostic interactions. This is attributed to the strong trans influence ligand (H, CO, ...
متن کاملNickel complexes of a bis(benzimidazolin-2-ylidene)pyridine pincer ligand with four- and five-coordinate geometries.
The four- and five-coordinate complexes [(CNC)NiX(2)] (X = Cl, Br, I), [(CNC)NiX]PF(6) (X = Cl, Br) and [(CNC)NiCl]Cl·H(2)O have been isolated, where CNC is the bis(N-butylbenzimidazolin-2-ylidene)-2,6-pyridine pincer ligand. A five-coordinate geometry is rare for this class of complex. Where amenable, the complexes have been structurally characterised by single crystal X-ray diffraction studie...
متن کاملFour-coordinate, trigonal pyramidal Pt(II) and Pd(II) complexes.
We report herein the characterization of electrophilic, trigonal bipyramidal {[SiP(3)(R)]Pt(L)}(+) cations ([SiP(3)(R)] = [(2-R(2)PC(6)H(4))(3)Si]; R = Ph, (i)Pr) that feature weakly coordinated ligands including CH(2)Cl(2), Et(2)O, toluene, and H(2). A cationic toluene adduct that shows a close platinum aryl C-H σ-contact is perhaps most noteworthy in this context. For the isopropyl-substitute...
متن کاملSynthesis and Reactivity of Four- and Five-Coordinate Low-Spin Cobalt(II) PCP Pincer Complexes and Some Nickel(II) Analogues
Anhydrous CoCl2 or [NiCl2(DME)] reacts with the ligand PCPMe-iPr (1) in the presence of nBuLi to afford the 15e and 16e square planar complexes [Co(PCPMe-iPr)Cl] (2) and [Ni(PCPMe-iPr)Cl] (3), respectively. Complex 2 is a paramagnetic d7 low-spin complex, which is a useful precursor for a series of Co(I), Co(II), and Co(III) PCP complexes. Complex 2 reacts readily with CO and pyridine to afford...
متن کامل[(TMEDA)Co(NO)2][BPh4]: A versatile synthetic entry point to four and five coordinate {Co(NO)2}10 complexes
[(TMEDA)Co(NO)2][BPh4] reacts with Group 1 salts of various monoanionic ligands to yield four and five coordinate {Co(NO)2} complexes. The synthesis of the four coordinate complex of the form [{LX} Co(NO)2] via salt-metathesis reactions of [(TMEDA)Co(NO)2][BPh4] with [{ArNC(Me)CHC(Me)NAr} Li(OEt2)] (Ar 1⁄4 2,6-di-iso-propylphenyl) is reported. In addition [(TMEDA)Co(NO)2][BPh4] reacts with eith...
