Abstract

Reaction of dichloridotetrakis(dimethyl sulfoxide)ruthenium(II) and N-[3,5-di-tert-butyl-2-(trimethylsilyloxy)benzyl]-N,N-bis(2-pyridylmethyl)amine (BPPA-TMS) affords the thermodynamic product cis,fac-[RuCl₂(BPPA-TMS)(DMSO)] and kinetic product trans,mer-[RuCl₂(BPPA-TMS)(DMSO)]. The title complex, [RuCl₂(C₃₀H₄₃N₃OSi)(C₂H₆OS)]·2CH₂Cl₂, crystallizes as a dichloromethane disolvate, with two formula units in the asymmetric unit. The complex exhibits a distorted-octahedral geometry about the low spin d ⁶ Ru^II center. The BPPA-TMS ligand is coordinated in a facial fashion, with the DMSO ligand cis to the aliphatic nitrogen atom of the BPPA-TMS ligand. One of the two dichloromethane solvate molecules is disordered over two positions in a 0.695:0.305 ratio.
