Mitochondria as an important organ in eukaryotic cells produced energy through oxidative phosphorylation and also played an important role in regulating the apoptotic signal transduction process. Importantly, mitochondria like nuclei also contained the functional DNA and were very sensitive to anticancer drugs which could effectively inhibit the synthesis of nucleic acid, especially the product...

Facile ligand substitution is observed when the ruthenium-azide complex, [RuN(3)(Tp)(PPh(3))(2)] [Tp,HB(pz)(3), pz = pyrazol-yl, PPh(3) = triphenyl-phosphine] is treated with benzo-nitrile, yielding the title compound, [Ru(C(9)H(10)BN(6))(N(3))(C(7)H(5)N)(C(18)H(15)P)]. The asymmetric unit contains two crystallographically independent mol-ecules. In each one, the Ru(II) atom is six-coordinated ...

The synthesis and structure of palladium complexes of trisubstituted PTA derivatives, PTA(R3), are described. Water-soluble phosphine ligands 1,3,5-triaza-7-phosphaadmantane (PTA), tris(aminomethyl)phosphine trihydrobromide, tri(aminomethyl) phosphine, 3,7-dimethyl-1,5,7-triaza-3-phosphabicyclo[3,3,1]nonane (RO-PTA), 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (DAPTA), lithium 1,3,5...

In the title binuclear silver(I) complex, [Ag(2)Br(2)(C(18)H(15)P)(3)]·0.85C(4)H(8)O, the two independent silver(I) ions are briged by two bromide ions. One Ag(I) ion is coordinated by two triphenyl-phosphine groups with a square-planar geometry, while the second is coordinated by one triphenyl-phine group with a trigonal-planar geometry. The structure is very similar to that of the dichloro-me...

Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...

The title compound, [Ag(C(7)H(2)Br(3)O(2))(C(18)H(15)P)(3)], a silver(I) derivative of 3,5,7-tribromo-tropolone, has three triphenyl-phosphine ligands coordinated to the silver centre, whereas the 3,5,7-tribromo-tropolonate anion coordinates as a bidentate ligand. The compound is an example of a five-coordinate silver complex containing a bidentate ligand.

The title compound, [Ni(C(12)H(9)O)Cl(C(18)H(15)P)(2)]·CH(2)Cl(2), was synthesized from the reaction between 1-acetyl-4-chloro-naphthalene, NiCl(2)·6H(2)O and triphenyl-phosphine (PPh(3)) in ethanol. The compound contains one crystallographically unique nickel ion in a pseudo-square-planar geometry.

The title complex, [Os(C(6)F(5)S)(3)Cl(C(18)H(12)F(3)P)], displays a trigonal-bipyramidal Os(IV) coordination geometry with the S atoms of three thiol-ate ligands occupying the equatorial positions. The thiol-ate penta-fluoro-phenyl substituents are all placed above the equatorial plane, forming a claw-like cavity which accommodates the chloride ligand with a normal Os-Cl bond length. The phosp...

The title compound, [Pd(2)Cl(4)(C(8)H(11)O(2)P)(2)], is binuclear and disposed about a crystallographic centre of symmetry with a Pd⋯Pd distance of 3.4662 (17) Å. It has a similar geometry to that observed in the triphenyl-phosphite and triphenyl-phosphine analogues. The Pd-P bond length is ca 0.04 Å shorter than those in mononuclear PdCl(2)(P(OMe)(2)Ph)(2), possibly due to the lower trans-infl...

This work contributes to the systematic investigation of phosphines. In an attempt to deter­ mine the nature, shape, volume and direction of the lone pairs at the phosphorus atoms in phosphines, high resolution X-ray structure analyses of triphenylphosphine, tris(p-methoxyphenyl)phosphine, bis(2,4,6-triisopropylphenyl)phosphine, 1,1 -bis(diphenylphosphino)ethene and 4,5,6-triphenyl-4-phosphaspi...
