Abstract top

The coordination geometry of the Pd atom in the title compound, [Pd(SCN)2(C46H54N4O6)], is approximately square-planar. The N-heterocyclic carbene (NHC) metallacrown ether ligand binds to the Pd atom in a trans orientation through the carbene C atoms of the two imidazole rings and generates a 25-membered chelate ring. Two mutually trans S-bound thiocyanate ligands complete the coordination.

Comment top

N-Heterocyclic carbene (NHC) ligands have been found to be interesting substitutes for phosphine ligands and are employed with considerable success in coordination chemistry and various catalytic transformations (Herrmann et al., 2002; Hahn & Jahnke, 2008). Much interest has been devoted to the chemistry of metallacrown ethers formed by the chelation of bis(phosphorus-donor)polyether ligands to transition metals for a number of years (Alcock et al.,1976; Powell et al., 1981; Gray, 1995). Studies on these metallacrown ethers have shown that they can bind hard metal cations and such hard–soft bimetallic complexes are of interest as catalysts for organic reactions. Substitution of phosphine donors by NHCs has led to several examples of mixed NHC metallacrown ether ligands (Nielsen et al., 2003; Liu et al., 2007; Wang et al., 2005). Pd–NHC complexes are known to catalyze a wide range of useful cross-coupling reactions (Herrmann, 2002; Kantchev et al., 2007). However, we were surprised that no Pd–NHC metallacrown ether complexes have been described to date and we present here the first synthesis and crystal structure of the title Pd–NHC metallacrown ether complex.

In the title compound (Fig. 1), a 25-membered Pd–NHC metallacrown ether complex adopting a trans-conformation is formed by a bidentate chelate bis(carbene) ligand with a long flexible linkage and a Pd(II). The coordination geometry at Pd is approximately square planar with the C1–Pd–C35 angle of 178.6 (3)° and the S1–Pd–S2 angle of 178.6 (3)°. The two benzene rings linked with ether oxygen atoms form a dihedral angle of 81.20°. The dihedral angle of the NHC rings is 39.38°.

Experimental top

A mixture of 1,20-di(1-mesitylimidazolium)-4,5,16,17-dibenzo-3,6,9,12,15,18-hexaoxaeicosane dichloride (83.2 mg, 0.10 mmol) prepared by literature procedures (Pedersen, 1967; Haque & Rasmussen, 1994) and silver(I) oxide (27.6 mg, 0.12 mmol) in 5 ml of CH2Cl2 was stirred at room temperature for 2 h. The reaction mixture was filtered and washed with CH2Cl2 (5 ml × 2). The combined filtrate was reduced to 5 ml under vacuum. [PdCl2(MeCN)2] (25.8 mg, 0.10 mmol) in CH2Cl2 (3 ml) was added to the resulting solution and stirred at room temperature for 2 h, then KSCN (97 mg, 1 mmol) was added and stirred over night. The reaction mixture was filtered and washed with CH2Cl2 (5 ml × 2). The combined solution was evaporated under reduced pressure to leave a raw product, which was purified by flash chromatography on silica gel (CH2Cl2) to give a yellow solid. Single crystals suitable for X-ray diffraction were obtained at ambient temperature by slow evaporation of an Et2O solution over a period of several days.

Refinement top

All H atom were positioned geometrically with C—H = 0.93 Å (aromatic) or 0.96 Å (methyl) and refined using a riding model with 1.5 Ueq(C) for methyl and Uiso(H) = 1.2 Ueq(C) for others.

Special details top

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.
