trans-Tetracarbonylbis(triphenylphosphane-κP)molybdenum(0)

چکیده
The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits significantly different Mo-P-C-C torsion angles ranging from 2.6 (2) to 179.4 (1)°, most likely due to steric inter-actions based upon their positions relative to the carbonyl ligands.

In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes that are trans to each other. The Cr atom and two carbonyl groups are on a twofold axis. The benzene rings attached to the phospho-rus atom make dihedral angles of 80.32 (5), 52.91 (5) and 83.80 (5)° with each other. In the crystal, C-H⋯O and ...

In the title coordination polymer, [Ag2Cl2(C10H8N2)(C18H15P)2] n , the Ag(I) cation is coordinated by a 4,4'-bi-pyridine N atom, a tri-phenyl-phosphane P atom and two Cl(-) anions in a distorted tetra-hedral geometry. The 4,4-bi-pyridine and Cl(-) anions bridge the Ag(I) cations, forming polymeric chains running along [21-1]. In the crystal, weak C-H⋯Cl inter-actions link the polymeric chains i...

The title compound, [FePt(C12H10P)(C13H13Si)(C18H15P)2(CO)3]·0.5CH2Cl2, represents an example of a phosphido-bridged heterobimetallic silyl complex; these are inter-esting precursors for the coordination and activation of small unsaturated organic mol-ecules. The μ2-PPh2 ligand spans the iron and platinum atoms, which are connected via a metal-metal bond of 2.7738 (4) Å. In contrast to most oth...

The title compound, [Pd(SC6H4F-p)Cl(PPh3)2]·0.5CH3OH, features a Pd(II) complex with two tri-phenyl-phosphane (PPh3) ligands arranged in a trans conformation, with one chloride and one 4-fluoro-benzene-thiol-ate ligand completing the coordination sphere, giving rise to a slightly distorted square-planar geometry of the Pd(II) ion. The methanol solvent mol-ecule is disordered about an inversion ...
