In the neutral title compound, [Re(C(6)H(5)NO)(C(13)H(9)NO(2))(CH(3)O)(C(18)H(15)P)], an 18-valence-electron complex, the Re(V) ion lies in an octa-hedral coordination geometry with the tridentate dianionic Schiff base 2-(2-oxidobenzyl-idene-amino)phenolate ligand occupying three equatorial coordination sites, and with the triphenyl-phosphine ligand situated trans to the imine N atom. The Re(V)...

In the title compound, [Ru(C(9)H(10)BN(6))Cl(C(3)H(4)N(2))(C(18)H(15)P)], the Ru(II) atom is coordinated by an N,N',N''-tridentate hydrido-trispyrazolylborate (Tp) ligand, a pyrazole (HPz) mol-ecule, a chloride ion and a triphenyl-phosphine ligand, resulting in a distorted RuClPN(4) octa-hedral coordination for the metal ion: the tridentate N atoms occupy one octa-hedral face and the Cl and P a...

The title compound, [Au(C(18)H(27)ClN(3))(C(18)H(15)P)](NO(3))(2), is a coordination complex of gold(I) triphenyl-phosphine with the N atom in the quinoline ring of the common anti-malarial compound chloro-quine (CQ). The pendant diethyl-amino group of the CQ ligand was found to be protonated. The complex exhibits a nearly linear coordination geometry around the Au(I) atom [N-Au-P = 176.94 (6)°...

Monodisperse, size-controlled Ni-P nanoparticles were synthesised in a single step process using triphenyl-phosphane (TPP), oleylamine (OA), and Ni(II)acetyl-acetonate. The nanoparticles were amorphous, contained ~30 at% P and their size was controlled between 7-21 nm simply by varying the amount of TPP. They are catalytically active for tailored carbon nanotube growth.

A range of thio- and seleno-phosphonium cationic complexes [RE(PR'3)](+)[X](-) (R = Me, Ph; E = S, Se; X = GaCl4, SbF6) have been synthesised and structurally characterised. Reaction of [PhSPPh3][GaCl4] and [PhSePPh3][GaCl4] with P(t)Bu3 results in the ready transfer of the "RS(+)" and "RSe(+)" fragments from PPh3 to the stronger electron donor P(t)Bu3. NMR experiments combined with an Eyring a...

The hypoxia of the tumor microenvironment (TME) seriously restricts photodynamic therapy (PDT) effect conventional type-II photosensitizers, which are highly dependent on O2. In this work, a new type-I photosensitizer (TPE-TeV-PPh3) consisting tetraphenylethylene group (TPE) as bioimaging moiety, triphenyl-phosphine (PPh3) mitochondria-targeting group, and telluroviologen (TeV2+) reactive oxyge...

In the mononuclear title complex, [CuI(C(4)H(9)N(3)S)(C(18)H(15)P)(2)], the Cu(I) ion displays a distorted tetra-hedral coordination geometry involving two P atoms of two triphenyl-phosphane mol-ecules, one S atom of a 1-(propan-2-yl-idene)thio-semicarbazide mol-ecule and one iodide ion. In the crystal, C-H⋯π inter-actions [C-H⋯centroid distances = 3.443 (3) and 3.788 (3) Å] and N-H⋯S hydrogen ...

In the title Cu(I) compound, [Cu(C6H5N5)(C18H15P)2]BF4, the Cu(I) cation is N,N'-chelated by a 5-(pyridin-2-yl)-1H-tetra-zole ligand and coordinated by two triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The tetra-zole and pyridine rings are essentially coplanar [dihedral angle = 4.1 (3)°]. The tetra-fluoridoborate anion links to the complex cation via an N-H⋯F hydrogen bond.
