Di-μ-methoxido-κ⁴O:O-bis[bis(3-methyl-5-phenyl-1H-pyrazole-κN²)copper(II)] bis(perchlorate)

H. He and A. G. Sykes

In the title complex, [Cu(CH₃O)₂(C₄₀H₄₀N₈)](ClO₄)₂, two copper ions are bridged by two methoxide O atoms. Each Cu^II is further coordinated by two neutral 3-methyl-5-phenyl-1H-pyrazole ligands and adopts a distorted square-planar geometry. The two perchlorate anions lie on opposite sides of the Cu₂O₂ plane and there is evidence for interaction between two of the O atoms from each perchlorate anion with the Cu^II centers.

Comment top

3-methyl-5-phenyl-1H-pyrazole has been widely used as starting material for the preparation of the trispyrazolylborate anion, and as a very good ligand for modeling complexes of several metalloenzymes (Tekeste & Vahrenkamp 2007; Jacobsen & Cohen, 2004; Puerta & Cohen, 2003; Parkin, 2004). However, its interaction with transition metal ions is rare. Reported here is the single-crystal structure of a dicopper(II) complex of this ligand.

In the title compound (I) two methoxide anions hold two copper ions together with O as the bridging atoms. The distance between Cu1 and Cu2 is 2.9583 (7) Å. Each copper ion is further coordinated by two pyrazolyl N atoms. Copper adopts an approximate square planar geometry. Atoms N1, N2, N3, N4, Cu1, and Cu2 are almost coplanar with a torsion angle of 3.4 (3)° between the N1/N2/Cu2 and N3/N4/Cu1 planes. The two bridging methoxyl groups are located on either side of this plane. The torsion angles between the O1/Cu1/Cu2 and O2/Cu1/Cu2 planes and that containing the atoms N1/N2/N3/N4/Cu1/Cu2 are 12.30 (16)° and -12.30 (16)°, respectively. The Cu1/O1/Cu2/O2 ring is also planar with an r.m.s. deviation from the best fit meanplane of 0.0002. The O4, O9 and O3, O8 atoms from the two perchlorate anions point towards the Cu1 and Cu2 centers with distances 2.722 (3), 2.755 (3), 2.790 (3), and 2.869 (3) Å for O3—Cu2, O4—Cu1, O8—Cu2, and O9—Cu1, respectively. This indicates some level of interaction between the perchlorate anions and the Cu^II cations.

Experimental top

3-methyl-5-phenyl-1H-pyrazole (0.16 g, 0.1 mmol), prepared according to the literature (Puerta & Cohen, 2003), was dissolved in dichloromethane (10 ml) at room temperature. To this solution, copper(II) perchlorate hexahydrate (0.18 g, 0.05 mmol) in methanol (2 ml) was added. The resulting blue solution was stirred for two hours. The mixture was filtered and the filtrate kept at room temperature. Blue crystals were obtained after one week by slow evaporation.

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.
