A solution of [Cu2(DPipG2p)]2[PF6]2 (262 mg, 0.2 mmol) (Herres et al., 2004b) in MeCN (50 ml) was treated at room temperature with pure dioxygen. After the mixture had been left to stand for one week, dark-blue crystals suitable for X-ray diffraction were obtained. IR (KBr, cm−1): 3446 [vw, ν(O–H)], 2937 (s), 2852 (s), 1533 [versus, ν(C═N)], 1495 [s, ν(C═N)], 1446 (versus), 1371 (s), 1335 (m), 1253 (m), 1226 (m), 1205 (m), 1164 (w), 1141 (m), 1110 (m), 1070 (w), 1020 (m), 948 (m), 917 (w), 839 [versus, ν(P–F)], 744 (m), 622 (w), 597 (w), 557 (m), 487 (w).
H atoms attached to C atoms were placed at idealized positions, riding on their attached C atoms, with Uiso(H) values of 1.2Ueq(C) and 1.5Ueq(Cmethyl). All CH3 groups were allowed to rotate but not to tip. The O—H distance of the hydroxo group was restrained to 0.84 (1) Å. The disordered piperidine group at N6 was treated with a split model. Geometric parameters derived for the isotropically refined minor positions are less reliable.

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. |

The activation of dioxygen by tyrosinase-like CuI complexes plays an important role in biological and synthetic oxidation processes. Recent efforts have been directed towards elucidating the structure–reactivity relationship of the underlying Cu2O2 species through synthetic model systems (Tolman, 1997; Que & Tolman, 2002). In search of bifunctional N-atom donor ligands able to stabilize unusually high metal oxidation states, we extended our interests towards guanidyl-type systems (Herres et al., 2004a). The first derivative, the bis-tetramethylguanidinopropylen ligand (btmgp), and its complexes with copper, iron and nickel were investigated with regard to their coordination chemistry (Harmjanz, 1997; Waden, 1999; Pohl et al., 2000; Schneider, 2000; Herres, 2002). We have now examined the reaction behaviour of mono- and binuclear copper(I) complexes containing the (DPipG2p) ligand towards molecular oxygen. The reaction products have been identified as rare examples of alkoxo-bridged binuclear copper complexes, demonstrating that the bidentate ligand has been hydroxylated in an unprecedented manner (Herres et al., 2004b). Another product, the bishydroxo-bridged binuclear copper title complex, [Cu2(DPipG2p)2(µ-OH)2][PF6]2, will be discussed here.
The geometric centre of the cation lies on a crystallographic inversion centre, and thus the resulting Cu2O2 core is strictly planar. The Cu atom is coordinated in a planar quadratic manner by two guanidinyl N atoms and the two bridging O atoms. The deviation of the Cu atom from the N2O2 plane is 0.036 (1) Å, and the chelate heterocycle adopts a chair conformation. The presence of the hydroxo H atom was confirmed from Fourier maps. According to the existing (\-OH) bridges the Cu.·Cu and Cu—O distances of 3.0740 (6) and av. 1.935 (2) Å are clearly elongated compared with those of bis-µ-oxo-bridged Cu2O2 moieties, which range from 2.743 (1) to 2.906 (1) Å, and from 1.796 (6) to 1.865 (3) Å, respectively. Similar observations hold for related Fe complexes (Que & Tolman, 2002). As pointed out by Que & Tolman (2002), the significant differences between the short [in M2(µ-O)2] and long [in M2(µ-OH)2] M—O distances are obviously a suitable measure to distinguish between these two species. The N6 piperidine group is disordered over two sites with occupation factors 0.823 (6) and 0.177 (6). Fig. 1 displays only the major position. The packing is determined by intermolecular hydrogen bonds between the cation and the hexafluorophosphate anions [C14—H14A.·F16(-x + 2, −y + 2, −z + 1) with H···F = 2.275 (4) Å and C—H···F = 170.4 (2)°, C3—H3A···F12(x, y, z) with H···F = 2.384 (5) Å and C—H···F = 160.7 (3)°, and C251—H25A.·F15(x − 0.5, −y + 0.5 + 1, z − 0.5) with H···F = 2.406 (4) Å and C—H···F = 142.9 (3)°]. The shortest intramolecular interaction is C241—H125D.·N6 [H.·N = 2.124 (3) Å]. All these values are normalized for a C—H distance of 1.08 Å.
