Bis(dicyclohexylphenylphosphine)iodidosilver(I) pyridine monosolvate

B. Omondi and R. Meijboom

Abstract top

The structure of the title compound, [AgI(C18H27P)2]·C5H5N, shows a trigonal-planar coordinated AgI atom within a distorted IAgP2 donor set. The pyridine solvent molecule is only associated with the complex via very weak intermolecular C-H...N interactions.

Comment top

Stoichiometric reactions of silver(I) with tertiary phosphines often results in silver(I) complexes of the type [AgXLn] (L = tertiary phosphine; n = 1 - 4 ; X = coordinating or non-coordinating anion). These complexes display a diversity of structural types, and reviews on this topic have been published (Meijboom et al., 2009 and refs. therein). A 1:2 stoichiometric ratio generally results in monomeric complex [AgX(PR3)2]/[Ag(PR3)2]+X- or dimeric complex [{AgXL2}2] (Bowmaker et al., 1996; Meijboom et al., 2009) depending on the donor properties of the phosphine ligand, the bulkiness of the ligand substituents and the donor properties of the anion (Bowmaker et al., 1996).

The title complex crystallizes as mononuclear units in the P21/n space group with one [AgBr{PCy2Ph}2] complex and one pyridine molecule in the asymetric unit as expected for the bulky and fairly basic dicyclohexylphenyl phosphine ligands (Lin et al., 1993; Alyea et al., 1982; Bowmaker et al., 1993). This type of [AgX(PR3)2] coordination was also observed for X = CN, I, Br, C1, SCN or NCO, most of which were found to be isomorphous in the monoclinic C2/c space group (Bowmaker et al., 1996).

The iodide anion is unsymmetrically coordinated to the silver with I-Ag-P angles of 105.00 (2) and 122.75 (2)°. The P-Ag-P angle is 131.59 (3)° with the I-Ag distance being 2.7725 (5) Å. These angles and distances are comparable to those of the thiocyanate analogue ([AgSCN(P{Cy3})2] I-Ag-P = 104.60 (8) and 123.69 (8)° and P-Ag-P = 131.51 (7)°) (Bowmaker et al., 1996) both of which have the disposition of the two phosphine ligands fairly different. This fits with trend that relates M-X distances and P-M-P angles as shown by Bowmaker et al. (1996) for complexes with bulky phosphines. The three-co-ordinate (P2AgX) silver environment is planar with the sum of the I-Ag-P and P-Ag-P angles being 359.3°. The pyridine solvate interacts very weakly with the silver(I) complex through C-H···N interactions.

Despite the number of structural reports of [AgXLn] complexes, their solution behaviour, initiated by Muetterties & Alegranti (1972), has always shown that the coordinating ligands were labile in all complexes studied. Rapid ligand-exchange reactions have been reported for all 31P NMR spectroscopic investigations of ionic AgI monodentate phosphine complexes, thus making NMR spectroscopy of limited use for these types of complexes.

Experimental top

Silver iodide (0.130 g, 0.43 mmol) and dicyclohexylphenylphosphine (1.009 g, 0.86 mmol) were suspended in pyridine (5 ml). The mixture was heated to give a clear solution. Colourless crystals of the title compound suitable for X-ray crystallography were obtained by slow evaporation.

Refinement top

All hydrogen atoms were positioned geometrically, with C–H = 0.97 Å, and allowed to ride on their parent atoms with Uiso(H) = 1.2Ueq(C).

Special details top

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