The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru(3)(C(25)H(22)P(2))(C(19)H(17)PS)(CO)(9)]·CH(2)Cl(2), contains one triangulo-triruthenium complex mol-ecule and one half-mol-ecule of the dichloro-methane solvent. The dichloro-methane solvent mol-ecule lies across a crystallographic inversion center leading to the mol-ecule being disordered over two positions of equal occupa...
The title solvated complex, [Ru(η(5)-C5H5)(N3){P(C6H5)3}2]·0.5CH2Cl2, displays a typical piano-stool geometry about the Ru(II) atom. The bond lengths and angles of the cyclo-penta-dienyl and phosphane ligands are very similar to that of the unsolvated complex [Taqui Khan et al. (1994 ▶). Acta Cryst. C50, 502-504]. The azide anion displays similar N-N distances of 1.173 (3) and 1.156 (3) Å and h...
Most of the systems for photochemical hydrogen production are not stable and suffer from decomposition. With bis(bidentate) tetraphosphane ligands the stability increases enormously, up to more than 1000 h. This stability was achieved with a system containing osmium(ii) as a light harvesting antenna and palladium(ii) as a water reduction catalyst connected with a bis(bidentate) phosphane ligand...
There is growing interest in compounds containing functionalized E=E multiple bonds (E=Si, Ge, Sn, Pb) because of their potential to exhibit novel physical and chemical properties. However, compounds containing multiple functionalizations are rare, with scarcity increasing with increasing degree of substitution. The first ditetrelene R2 E=ER2 in which the E=E bond is substituted by four heteroa...
The title phosphane, C(32)H(38)P(4) or (Ph(2)P)(2)P(P(t)Bu(2)), has a P atom that is linked to another three P atoms in a pyramidal configuration; the P-P distances in the range 2.2231 (7)-2.2446 (7) Å indicate that the P-P bonds are single bonds.
