The asymmetric unit of the title compound, [Ru3(C19H17P)(C25H22P2)(CO)9], consists of two independent mol-ecules. The bis-(di-phenyl-phosphan-yl)methane ligand bridges an Ru-Ru bond and the benzyl-diphenyl-phosphane ligand binds to the third Ru atom. The Ru-Ru bond cis to the benzyl-diphenyl-phosphane ligand is the longest of the three Ru-Ru bonds in both mol-ecules. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming layers parallel to the ac plane. C-H⋯π contacts further stabilize the crystal packing.

Binuclear methylphosphinidine complexes of cyclopentadienylruthenium carbonyls: effects of the higher ligand field strength of ruthenium derivatives relative to iron derivatives.

The structures and energetics of the binuclear methylphosphinidene complexes of cyclopentadienylruthenium carbonyls of the type [MePRu(CO)Cp] ( = 4, 3, 2, 1) have been investigated for comparison with their previously studied iron analogues. For the tetracarbonyls and tricarbonyls [MePM(CO)Cp] ( = 4, 3) substituting ruthenium for iron has relatively little effect on the energetically preferred structures. Thus such structures have two-electron donor bridging MeP groups with no metal-metal bond for the tetracarbonyls and a metal-metal single bond for the tricarbonyls.

The field-induced quantum-disordered state of layered honeycomb magnet α-RuCl is a prime candidate for Kitaev spin liquids hosting Majorana fermions and non-Abelian anyons. Recent observations of anomalous planar thermal Hall effect demonstrate a topological edge mode, but whether it originates from Majorana fermions or bosonic magnons remains controversial. Here, we distinguish these origins from combined low-temperature measurements of high-resolution specific heat and thermal Hall conductivity with rotating magnetic fields within the honeycomb plane.

Dehydrogenation of ammonia borane to well-defined products is an important but challenging reaction. A dinuclear ruthenium complex with a Ru-Ru bond bearing a diazadiene (dad) unit and olefins as non-innocent ligands catalyzes the highly selective formation of conjugated polycondensed borazine oligomers (BNH), predominantly BNH, the BN analogue of superbenzene.

The study disclosed that the reactivities of [Ru (PPh)Cl] and [Ru(PPh)(CO)(H)Cl] precursors toward a trimethoxyarylimino-phenol derivative are sensibly different. The former promotes methoxy demethylation reaction affording a [Phenolato-Ru-Phenolato] unit, while the latter containing π-acidic CO and hydride as coligands leads to C-H activation reaction, generating a [Phenolato-Ru-Aryl] unit. Notably, the oxidized analogues of these two forms produce antiferromagnetically coupled [Ru-phenoxyl] and paramagnetic [Ru-phenoxyl] forms, which exhibit diverse reactivities.

From paddlewheel starting reactants Ru(R'CO), a family of edge-sharing bi-octahedral (ESBO) diruthenium(III,III) compounds has been prepared, formulated as Ru(μ-OCR')(μ-OR)(η-L) (1-10) [R' = CH, R = CH, L = acac (1), tfac (2); R' = CH, R = CHCH, L = hfac (3); R' = CHCH, R = CH, L = acac (4), tfac (5); R' = CHCH, R = CHCH, L = hfac (6); R' = CHCl, R = CH, L = tfac (7); R' = CHCl, R = CHCH, L = hfac (8); R' = CH, R = CH, L = tfac (9); and R' = H, R = CH, L = acac (10); here, acac, tfac and hfac represent acetylacetone, trifluoroacetylacetone and hexafluoroacetylacetone, respectively]. Compounds 1-10 have a similar ESBO coordination geometry of the Ru(μ-OCR')(μ-OR)Ru core with a Ru-Ru center chelated and bridged by two μ-OCR' and two μ-OR in a manner, and each Ru center is also coordinated with a η-L bidentate ligand. The Ru-Ru distances fall in the range of 2.
