The title compound, [Cu(C₃F₅O₂)(C₃H₉OP)₄](C₃F₅O₂), comprises a cationic Cu^II complex and a disordered pentafluoropropionate counter-ion. The metal atom has a distorted square-pyramidal coordination environment formed by four O atoms originating from trimethylphosphine oxide molecules and the remaining one belonging to the monodentate pentafluoropropionate anion, which is situated in the basal plane of the pyramid. The molecules are held together in the crystal by a net of weak C—H⋯O and C—H⋯F hydrogen bonds. The counter anion is disordered over two sets of sites in a 0.629 (5):0.371 (5) ratio.

Comment top

During our ongoing studies on metal complexes with tertiary phosphines (Szymańska et al., 2007) and perfluorinated carboxylates (Piszczek et al., 2008; Szymańska et al., 2009) suitable for chemical vapour deposition (CVD), the title compound was accidentally isolated. It is the first report on the crystal structure of a Cu complex with trimethylphosphine oxides. There is however some literature on coordination compounds of trimethylphosphine oxide ligands with other metals from the first transition series such as: Sc(III) (Hill et al., 2003), Ti(III) (Johnson & Bergman, 2001), V(III) (Veige et al., 2003), Fe(II) (Cotton et al., 1991), Co(II) (Edelmann & Behrens, 1986), Ni(II) (Klein et al., 1999), Zn(II) (Hlavinka & Hagadorn, 2005).

Furthermore, there are also only two reports on crystal structures of Cu^II complexes containing coordinating pentafluoropropionate ions (Jiang et al., 1998; Zhang et al., 1999).

The title compound has one monocationic Cu^II complex and one pentafluoropropionate counter-ion present in the asymmetric unit (Fig.1). The geometry around the Cu^II ion is a distorted square-pyramid formed by four O atoms originating from trimethylphosphine oxide molecules and one from the monodentate pentafluoropropionate ion, which is located in the base plane of the pyramid. The corresponding bond lengths and angles are presented in Table 1. The geometrical features of the ligands are in good agreement with reported values. The counter-ion is disordered over two positions with refined site occupancies of 0.629 (5):0.371 (5). There are weak intramolecular C—H···O interactions between the methyl groups of three distinct trimethylphosphine oxides (P1, P2 and P4) involving the atoms C3, C5 and C10, that act as donors, and O5 (from the counter-ion), as well as O4 and O3 (from the oxide ligands), that act as acceptors, respectively (Table 2). The C9 methyl group from P3 however, interacts with the counter-ion by weak C9—H9A···F7A hydrogen bonding with a C···F distance of 3.322 (6) Å, and a C—H—F angle of 150°. The packing is further stabilized by numerous weak intermolecular C—H···O and C—H···F interactions.

Experimental top

(C₂F₅COO)₂Cu (1.04 mmol) was placed in a Schlenk tube, dissolved in 25 ml of freshly distilled acetonitrile, and copper powder (5 mmol) was added. The obtained suspension was stirred until the solution was pale yellow. Then PMe₃ (2.1 ml of a 1 M THF solution) was added and the reaction mixture was stirred for 18 h at ambient temperature, and filtered. The solvent was evaporated under reduced pressure, yielding [Cu₂(PMe₃)₂(µ–C₂F₅CO₂)₂] as a pale yellow, viscous oil. Crystals of the title Cu^II complex suitable for X-ray studies were obtained after a few months, presumably upon slow oxidation by diffused air.

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.
