The title compound, [Fe(2)(C(3)H(6)S(2))(C(18)H(15)P)(2)(CO)(4)], which might serve as an active-site model of [FeFe]-hydrogenase, contains two fused Fe/S/C/C/C/S six-membered rings, one of which has a chair conformation and the other a boat conformation. Each Fe atom is coordinated by two carbonyl ligands, a triphenyl-phosphane ligand and a bis-bidentate dithiol-ate ligand, and also forms an F...

A recent trend in homogeneous gold catalysis has been the development of oxidative transformations relying on Au(I)/Au(III) redox cycling. Typically, phosphine-supported Au(I) precatalysts are used in the presence of strong oxidants to presumably generate phosphine Au(III) intermediates. Herein, we disclose that such Au(III) complexes can undergo facile C(aryl)-P reductive elimination to afford...

In the centrosymmetric title complex, [Cu(2)(C(12)H(10)N(4))(C(18)H(15)P)(4)](BF(4))(2)·2CH(2)Cl(2), the Cu(I) atom adopts a distorted tetra-hedral geometry, defined by two P atoms from two triphenyl-phosphine ligands and two N atoms from a pyridine-2-carbaldehyde azine ligand. The two Cu atoms are bridged by the centrosymmetric pyridine-2-carbaldehyde azine ligand. The F atoms of the tetra-flu...

The title complex, [Pd(C(2)H(2)N(3)S(2))(2)(C(18)H(15)P)(2)]·2C(2)H(6)OS·0.5H(2)O, was obtained from the reaction of trans-[(Ph(3)P)(2)PdCl(2)] with 5-amino-1,3,4-thia-diazole-2-thione (SSNH(2)) in a 2:1 molar ratio. The Pd(II) atom, located in a crystallographic center of symmetry, has a square-planar geometry with two triphenyl-phosphine P-coordinated mol-ecules and two SSNH(2) ligands with t...

The reaction of [RuCl(C(9)H(10)BN(6))(C(18)H(15)P)(2)] with benzo-phenone imine in methanol, in the presence of sodium azide, leads to the formation of the title compound, [Ru(C(9)H(10)BN(6))(N(3))(HN=CPh(2))(C(18)H(15)P)]·C(4)H(10)O, which crystallizes as the diethyl ether solvate. In the crystal structure, the Ru atom is coordinated by three N atoms of one hydridotris(pyrazoly)borate anion, o...

From literature data on partition coefficients and in some cases solubilities in nonaqueous solvents we have been able to determine Abraham descriptors for several series of organophosphorus compounds including the dialkyl- and diaryl-phosphates (dialkylphosphoric acids), trialkyl- and triphenyl-phosphates, dialkylphosphinic acids and diphenylphosphinic acid, trialkyl- and triaryl-phosphine oxi...

The centrosymmetric title complex, [Pd(6)(C(6)H(5)Te)(4)Te(4)(C(18)H(15)P)(6)]·9C(6)H(6), contains two Pd(3)Te(2) cores that are joined into a cyclic hexa-nuclear complex by two bridging PhTe(-) groups. Each Pd(II) atom is coordinated by one triphenyl-phosphine ligand, one phenyl-tellurolate mol-ecule and two telluride ligands: two of the PhTe(-) ligands act as terminal ligands and two as bridg...

The title compound, {[Cu(C(10)H(14)N(4)Se)(2)(H(2)O)](BF(4))(2)·2C(18)H(15)PO·H(2)O}(n), has a polymeric structure where each Cu(II) ion adopts a square-pyramidal coordination constituted by four N atoms of pyrazole moieties in the equatorial plane and an axial O atom of a water mol-ecule. A pair of bis-(3,5-dimethyl-1H-pyrazol-4-yl) selenide ligands bridges the Cu(II) centres into a chain exte...
