[AuCl(PPh3)] (McAuliffe et al., 1979) (100 mg, 0.202 mmol)and 5-Ethynyl-1,10-phenanthroline (Ziessel et al., 1996) (40.4 mg, 0.02 mmol) were stirred in a solution of CH3ONa in MeOH (0.1 M, 15 ml) for 8 h. After filtration, the solid precipitate was washed with 2 ml MeOH and recrystallized by diffusion of n-hexane into its dichloromethane solution. Yellow crystals suitable for single-crystal X-ray analysis were obstained after 5 days.
All H atoms were included in calculated positions with C—H = 0.93 Å and with Uiso(H) = 1.2Ueq(C).
Acetylide-functionalized diimines have been used widely in the design of multi-component transition metal complexes composed of discrete redox and/or photoactive sub-units. (Pomestchenko et al., 2005; Ziessel et al., 1998) We have focused on such bridging ligands for the design of d–f bimetallic arrays by introducing d-block chromophores and f-block luminophores bound to acetylide and bipyridine/phenanthroline, respectively.
As shown in Fig. 1, the coordination geometry of Gold(I) is two-coordinate (linear), the Gold(I) atom is bound to (1,10-phenothrolin-5-yl)ethynyl as well as coordinated to P atom from triphenylposphine. The bond distance [2.013 (5) Å] of gold(I)–alkynyl is comparable to those observed in other Gold (I) acetylide complexes (Yam et al., 1999). The structure of (1,10-phenothrolin-5-yl)ethynyl is normal compared to the platinum compound (Xu et al., 2006). Unlike some Gold (I) acetylide complexes (Yam et al.,1999), no intermolecular Au···Au interaction is observed.

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. |

Acetylide-functionalized diimines have been used widely in the design of multi-component transition metal complexes composed of discrete redox and/or photoactive sub-units. (Pomestchenko et al., 2005; Ziessel et al., 1998) We have focused on such bridging ligands for the design of d–f bimetallic arrays by introducing d-block chromophores and f-block luminophores bound to acetylide and bipyridine/phenanthroline, respectively.
As shown in Fig. 1, the coordination geometry of Gold(I) is two-coordinate (linear), the Gold(I) atom is bound to (1,10-phenothrolin-5-yl)ethynyl as well as coordinated to P atom from triphenylposphine. The bond distance [2.013 (5) Å] of gold(I)–alkynyl is comparable to those observed in other Gold (I) acetylide complexes (Yam et al., 1999). The structure of (1,10-phenothrolin-5-yl)ethynyl is normal compared to the platinum compound (Xu et al., 2006). Unlike some Gold (I) acetylide complexes (Yam et al.,1999), no intermolecular Au···Au interaction is observed.
