S1. Comment

Binuclear complexes of silver with certain bidentate ligands are of great interest due to their rich luminescence and bonding properties. Several compounds of binuclear [Ag₂(µ₂-dppm)₂]²⁺ dications, counterbalanced by various anionic species have been reported previously (Ahrens & Jones, 1998; Lusser & Peringer, 1985; Ho & Bau, 1983). Herein we report the crystal structure of the title compound, [Ag₂(µ₂-dppm)₂](ClO₄)₂·2CH₃CN, (I).

The asymmetric unit of (I) consists of one-half of an [Ag₂(µ₂-dppm)₂]²⁺ dication, situated across a crystallographic inversion centre, an independent ClO₄⁻ anion and a acetonitrile solvent molecule. The structure of the dication with atomic numbering scheme is shown in Fig. 1. In the dication, the Ag atoms are doubly bridged by two dppm ligands, forming an eight-membered Ag₂P₄C₂ ring. The formation of M₂P₄C₂ ring (M = Cu, Ag, Au, Pt and Pd) has been reported previously (Ho & Bau, 1983; Neo et al., 1995; Van der Ploeg et al., 1979; Yam et al., 1997). The eight-membered ring displays a pseudo-chair conformation, as observed in [Ag₂(µ₂-dppm)₂](ClO₄)₂·2CH₂Cl₂ (Ahrens & Jones, 1998). In the ring, the Ag centers are two-coordinated to exhibit an approximately linear coordination geometry with a P1—Ag1—P2ⁱ [symmetry code: (i) −x, 1 − y, −z] angle of 174.95 (7)°. The intramolecular Ag···Ag contact is 3.0581 (12) Å, which is longer than that observed in other silver systems; 2.9532 (7) Å in [Ag₂(µ₂-dppm)₂](ClO₄)₂·2CH₂Cl₂ (Ahrens & Jones, 1998) and 2.987 (2) Å in [Ag₂(µ₂-dppm)₃](NO₃)₂·2H₂O (Hong et al., 1997). The Ag—P distances of 2.408 (2) and 2.410 (2) Å are comparable to those observed in the above two complexes.

The Ag1···N1 contact distance of 2.874 (10) Å is shorter than that observed [3.160 (6) Å] in [Ag₃{HC(PPh₂)₃}₂](ClO₄)₃·2CH₃CN (Che et al., 1992) but longer than that observed [2.552 (2) Å] in [Ag₃(dppm)₂(CH₃CN)₂](ClO₄)₂·(CH₃CH₂)₂O (Che et al., 1991). The Ag···O contact distances in (I) [Ag1···O12 = 3.071 (7) Å and Ag1···O12ⁱ = 3.367 (6) Å] lie in the range 2.959 (3)–3.514 (2) Å reported for [Ag₂(µ₂-dppm)₂](ClO₄)₂·2CH₂Cl₂ (Ahrens et al., 1998) but lie outside the range of 2.418 (5)–2.689 (6) Å reported for [Ag₂(dppm)₂(NO₃)₂] (Ho et al., 1983).

S2. Experimental

The title compound was synthesized by a modification of a literature procedure (Lusser & Peringer, 1985). The complex was obtained by the reaction between [Cu₂(µ₂-dppm)₂](ClO₄)₂ and AgCCC(CH₃)₃ in a 1:2 ratio in acetonitrile solution under anaerobic conditions for 24 h. Well formed colorless crystals suitable for X-ray diffraction measurements were grown by the slow diffusion of diethyl ether into a solution of acetonitrile at room temperature.

S3. Refinement

The H atoms were positioned geometrically (C—H bond lengths were fixed in the range 0.93–0.97 Å), assigned isotropic displacement parameters and allowed to ride on their respective parent C atoms.

Special details

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.
