Bis(2,2′-bipyridine)[1,9-bis(diphenylphos­phanyl)-1,2,3,4,6,7,8,9-octahydropyrim­ido[1,2-a]pyrimidin-5-ium]ruthenium(II) hexa­fluorido­phosphate dibromide di­chloro­methane disolvate monohydrate

In the cation of the title complex, [Ru(C₃₁H₃₂N₃P₂)(C₁₀H₈N₂)₂](PF₆)(Br)₂·2CH₂Cl₂·H₂O, the ruthenium ion is coordinated in a distorted octa­hedral geometry by two 2,2′-bi­pyridine (bpy) ligands and a chelating cationic N-di­phenyl­phosphino-1,3,4,6,7,8-hexa­hydro-2-pyrimido[1,2-a]pyrimidine [(PPh₂)₂-hpp] ligand. The tricationic charge of the complex is balanced by two bromide and one hexa­fluorido­phosphate counter-anions. The compound crystallized with two mol­ecules of di­chloro­methane (one of which is equally disordered about a Cl atom) and a water mol­ecule. In the crystal, one of the Br anions bridges two water mol­ecules via O—H...Br hydrogen bonds, forming a centrosymmetric diamond-shaped R⁴₂(8) motif. The cation and anions and the solvent mol­ecules are linked via C—H...F, C—H...Br, C—H...Cl and C—H...O hydrogen bonds, forming a three-dimensional network.

Chlorido(η⁶-N²-diphenylphosphanyl-N¹,N¹-diisopropyl-4-methoxybenz­amidine-κP)(triphenylphosphane-κP)ruthenium(II) trifluoromethansulfonate acetone disolvate

In the title compound, [RuCl(C₁₈H₁₅P)(C₂₆H₃₁N₂OP)](CF₃O₃S)·2C₃H₆O, the Ru^II ion is coordinated in a three-legged piano stool, half-sandwich-type geometry by a chlorido ligand, a tri­phenyl­phosphine and a tethered η⁶-(phenyl-p-O-meth­oxy) κ¹-P N-di­phenyl­phosphino N′-diisopropyl amidine ligand charge-balanced by a trifluormethansulfonate counter-anion. The η⁶-coordination mode of the arene incorporated into the structure was generated in situ after addition of methyl tri­fluoro­methane­sulfonate to the neutral η⁵-arene tethered precursor complex [RuCl(PPh₃)(η⁵:κ¹-OC₆H₄C(NiPr₂)=N-PPh₂)] in di­chloro­methane solution.
