[μ-1,3-Bis(diphenyl-phosphino)propane-κP:P']bis-[bromidogold(I)].

ABSTRACT: The title compound, [Au(2)Br(2)(C(27)H(26)P(2))], features linearly coordinated Au(I) atoms within P,Br-donor sets. The central portion of the mol-ecule is practically planar as quanti-fied by the Br-Au⋯Au-Br torsion angle of -169.9 (2)°. The P-Au-Br chromophores are twisted with respect to each other [dihedral angle = 52.3 (6)°]. The benzene rings on each P atom lie on either side of this plane. The Au atoms are positioned at the periphery of the mol-ecule, which facilitates the formation of Au⋯Au inter-actions [3.2575 (11) Å] that result in the formation of supra-molecular chains along the b-axis direction. The Au⋯Au inter-actions are responsible for the deviations from the ideal linear geometry for each Au atom.

Poly[bis-[μ-1,3-bis-(diphenyl-phosphan-yl)propane-κP:P']-di-μ-thio-cyanato-κS:N;κN:S-disilver(I)].

Project description:In the title coordination polymer, [Ag(2)(NCS)(2)(C(27)H(26)P(2))(2)](n), two centrosymmetrically related Ag(+) cations are linked by two thio-cyanate anions into binuclear eight-membered macrocycles. The Ag⋯Ag separation within the macrocycle is 5.4400 (6) Å. The distorted tetra-hedral coordination about each metal atom is completed by the P atoms of two bridging 1,3-bis-(diphenyl-phosphan-yl)propane ligands, forming polymeric ribbons parallel to the a axis.

catena-Poly[[(nitrato-κO,O')silver(I)]-μ-1,2-bis-(diphenyl-phosphino)ethane-κP:P'].

Project description:In the title chain compound, [Ag(NO(3))(C(26)H(24)P(2))](n), the bis-(diphenyl-phosphino)ethane (dppe) units link the Ag(+) ions into chains along [001]. A nitrate anion is coordinated to the Ag atom. There is a centre of symmetry at the mid-point of the ethane C-C bond and a twofold rotation axis passes through the Ag, N and terminal O atoms. Each Ag atom is four-coordinated in a distorted tetra-hedral geometry by two O atoms of the nitrate anion and two P atoms of dppe ligands. The two aromatic rings are oriented at a dihedral angle of 73.77 (3)°.

[1,3-Bis(diphenyl-phosphino)propane-?P,P']diiodido(perfluoro-propyl)rhodium(III) dichloro-methane solvate.

Project description:The structure of the title compound, [RhI(2)(C(3)F(7))(C(27)H(26)P(2))]·CH(2)Cl(2), at 110?(2)?K is an unusual example of a structurally characterized square-based pyramidal alkyl complex of rhodium(III). The Rh-C bond is relatively short at 1.996?(6)?Å. This short metal-carbon bond length is typical of perfluoro complexes of transition metals and illustrates the enhanced bond strength in these compounds.

μ-Propane-1,3-dithiol-ato-κS,S':S,S'-bis-[dicarbon-yl(triphenyl-phosphane-κP)iron(II)](Fe-Fe).

Project description: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 Fe-Fe bond [2.5167 (16) Å]. Together, the six bonded atoms form a very distorted octa-hedral arrangement.

trans-Bis(1,3-diphenyl-propane-1,3-dionato)(methanol)oxidovanadium(IV) methanol disolvate.

Project description:In the title compound, [V(C15H11O2)2O(CH3OH)]·2CH3OH, the V(IV) atom is coordinated by two 1,3-diphenyl-propane-1,3-dionate ligands and an oxide ligand in an axial position. The sixth position is occupied by the O atom of a methanol group bonded trans to the oxide atom. The octa-hedral geometry is significantly distorted, with the V(IV) atom lying 0.330?(3)?Å above the equatorial plane formed by the O atoms of the two ?-diketonate ligands. In the crystal, O-H?O hydrogen bonds between the coordinating methanol group in the complex and the two methanol solvent mol-ecules lead to the formation of polymeric chains along the c-axis direction. Weak C-H?O contacts are also observed.
