The title compound, [Ag(C7H2Br3O2)(C18H15P)3], a silver(I) derivative of 3,5,7-tribromo­tropolone, has three triphenyl­phosphine ligands coordinated to the silver centre, whereas the 3,5,7-tribromo­tropolonate anion coordinates as a bidentate ligand. The compound is an example of a five-coordinate silver complex containing a bidentate ligand.

Comment top

Recently, solid state studies containing the 3,5,7-tribromotropolone ligand have been reported (Steyl, 2007; Steyl & Roodt, 2006; Roodt et al., 2003; Crous et al., 2005), different metal centers such as Rh(I) and Pd(I) have been investigated. In this regard, we present a silver(I) tris(triphenylphosphine) complex of the 3,5,7-tribromotropolonato moiety.

The Ag—O bond distances are closely related in length while the Ag—P bond distances differ from each other, Table 1. A single phosphorous atom (P1) has a slight increase in bond distance compared to P2 and P3. Comparing the title compound to a similar tropolonato complex (Steyl & Hill, 2009) the Ag—O bond distances increases by ca 0.2 Å, while the Ag—P distances increased by ca 0.1 Å. This trend is indicative of the higher coordination number about the silver metal centre and the weaker coordination properties of the 3,5,7-tribromotropolonato moiety. The bidentate bite angle of the title compound is nearly 10 ° smaller than the related tropolonato or oxolato complex (Steyl & Hill, 2009; Dean et al., 2001).

In previous studies the longest Ag—O bond distance reported for the 3,5,7-tribromotropolonato moiety was ca 2.496 Å (Roodt et al., 2003), while in the title compound this bond length has increased to 2.630 (4) Å. The increase in coordination number of the silver moiety is a direct result of the weaker coordinating ability of the bidentate ligand compared to the related tropolonato complex, which contains only two triphenylphosphine ligands.

Experimental top

The title complex was synthesized by the addition of the sodium salt of 3,5,7-tribromotropolone (204 mg, 0.57 mmol) to an dichloromethane solution (10 ml) of the [Cu(PPh3)2NO3] (370 mg, 0.57 mmol). On slow evaporation of the solvent; crystals suitable for X-Ray crystallography was obtained. Yield: 400 mg (58%).

Refinement top

H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å and Uiso(H) = 1.2 times Ueq(C aromatic).

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.
