In the title complex, [Cu(C20H13BrN4)(C18H15P)2]BF4·0.5CH2Cl2, the copper(I) cation adopts a distorted tetrahedral arrangement, coordinated by two triphenylphosphine ligands and two N atoms of the potentially tridentate terpyridine ligand. One half-molecule of dichloromethane crystallizes with the complex. The chlorine atoms are disordered over two sites with occupancies fixed at 0.30 and 0.20 respectively. The N donor atom of the central pyridine interacts weakly with the copper centre at a distance of 3.071 Å.

4'-(2-bromo-5-pyridyl)2,2':6',2''terpyridine (100 mg) and bis-triphenylphosphine bis-acetonitrile copper(I) tetrafloroborate (194 mg) were stirred in dichloromethane (20 ml) under argon for 1 h. After the colour had changed from colourless to yellow, the solution was evaporated to dryness, redissolved in a mimimum of dichloromethane and crystals suitable for X-ray crystallography were grown by diffusion with diethyl ether. Yield (191 mg, 70%)
One half molecule of dichloromethane crystallizes with the compound (1) with the chlorine atoms disordered over two sites with occupancies of fixed at 0.30 and 0.20 respectively. The hydrogen atoms of this hemi-solvate were not included in the
All other H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.93 Å, Uiso=1.2Ueq (C) for aromatic and 0.97 Å, Uiso = 1.2Ueq (C) for CH2 atoms.To fully characterize a family of multi-nuclear ruthenium complexes (Loiseau et al., 2002) we undertook to synthesize the the key bridging ligand 2:6:2''':6'''tetra-2-pyridyl-4,5':2',2'':5'',4'''tetrapyridine. Initial attempts at the synthesis by nickel catalysed homocoupling of 4'-(2-bromo-5-pyridyl)2,2':6',2''terpyridine failed, presumably due to the free terpyridine unit sequestering the nickel from the catalyst (Loiseau et al., 2002). The title complex, (I), Fig 1, crystallized as part of this work. The copper(I) cation adopts a distorted tetrahedral arrangement with the additional pyridine interacting weakly with the copper centre at a distance of 3.071 Å). Two other structures of copper (I) terpyridine bis-triphenylphosphine complexes were found in the literature (Ainscough et al., 1994; Feng et al., 2002). In both of these structures, the terpyridine ligand coordinates through all three N atoms giving a pentacoordinate complex. Despite the long N14—Cu1 distance there is an interaction, albeit somewhat weak. If there were no interaction it is likely that the N14 nitrogen of the loosely bound pyridine ring would rotate to adopt a s-trans arrangement, which is much more commonly seen in uncoordinated polypyridine ligands (Fitchett et al., 2005).

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. |

To fully characterize a family of multi-nuclear ruthenium complexes (Loiseau et al., 2002) we undertook to synthesize the the key bridging ligand 2:6:2''':6'''tetra-2-pyridyl-4,5':2',2'':5'',4'''tetrapyridine. Initial attempts at the synthesis by nickel catalysed homocoupling of 4'-(2-bromo-5-pyridyl)2,2':6',2''terpyridine failed, presumably due to the free terpyridine unit sequestering the nickel from the catalyst (Loiseau et al., 2002). The title complex, (I), Fig 1, crystallized as part of this work. The copper(I) cation adopts a distorted tetrahedral arrangement with the additional pyridine interacting weakly with the copper centre at a distance of 3.071 Å). Two other structures of copper (I) terpyridine bis-triphenylphosphine complexes were found in the literature (Ainscough et al., 1994; Feng et al., 2002). In both of these structures, the terpyridine ligand coordinates through all three N atoms giving a pentacoordinate complex. Despite the long N14—Cu1 distance there is an interaction, albeit somewhat weak. If there were no interaction it is likely that the N14 nitrogen of the loosely bound pyridine ring would rotate to adopt a s-trans arrangement, which is much more commonly seen in uncoordinated polypyridine ligands (Fitchett et al., 2005).
