Di-μ-iodido-bis[bis(cyclohexyldiphenylphosphine-κP)silver(I)]

The title compound, [Ag₂I₂(C₁₈H₂₁P)₄], has a dimeric structure located on a twofold rotation axis with each tetrahedral Ag^I ion coordinated by two terminal phosphines and bridged by iodide ligands. Although this structural motif has been reported in bromide– and chloride–silver complexes, this is the first reported dimeric iodide–silver complex with monodentate phosphine.

Comment top

The 1:2 AgI:PCyPh₂ dimeric complex is similar to the reported triphenyphosphine complexes with chlorine or bromine (Cassel, 1979; Bowmaker et al.,1993; Teo & Calabrese, 1976) and the 5-phenyldibenzophosphine complex with chloride (Attar et al., 1991). The 1:2 AgI:PCyPh₂ dimeric complex is the first reported complex of this type with bridging iodine and monodentate phosphine. The molecule is located on a twofold axis.

Experimental top

Synthesis of [Ag(PCyPh₂)₂I]₂: 1 equivalent of AgI and 2.1 equivalents of diphenylcyclohexylphosphine were added in a vial containing anhydrous methylenechloride.The mixture was allowed to stir for 3 h at room temperature in darkness. Colorless crystals were grown by slow cooling of a saturated methylenechloride solution from ambient to 273 K in the dark. (yield 54%).

Special details top

Experimental. Data collection is performed with four batch runs at φ = 0.00 ° (600 frames), at φ = 90.00 ° (600 frames), at φ = 180 ° (600 frames) and at φ = 270 ° (600 frames). Frame width = 0.30 ° in ω. Data is merged, corrected for decay, and treated with multi-scan absorption corrections.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
