Comment
=======

Crystals of the title compound were obtained as a side-product in the preparation of \[(Ph-BIAN)Cu(I)(Ph~3~As)~2~\]\[PF~6~\] (Ph-BIAN = Bis(phenyl-imino)acenaphthene) in methylene chloride solution. To identify this compound a single-crystal structure analysis was performed.

The title compound contains \[(Ph~3~As)~4~Cu\]^+^ ions which are disposed about crystallographic threefold axes, the metal atom lying on a special position of symmetry *3* is coordinated by two independent ligands. One of it is totally independent, whereas the other three are symmetry-related completing the nearly regular tetrahedral environment of the copper atom. The bond angles are 109.30 (2) and 109.65 (2) ° for As1---Cu1---As2 and As1---Cu1---As1\', respectively. Two independent phosphorus and fluorine atoms are found. The Cu---As2 bond of the independent (axial) arsine ligand is significantly shorter than the value for the off-axis Cu---As1 bonds (2.5044 (9) *versus* 2.5472 (5) Å). A similar distortion was previously found for the analogous salts \[(Ph~3~P)~4~Cu\]^+^ (with ClO~4~^-^ or PF~6~^-^ as anions), which also crystallize in the same space group (Bowmaker *et al.*, 1990, Engelhardt *et al.*, 1985).

Experimental {#experimental}
============

The title compound was isolated as a side-product in the preparation of \[(Ph-BIAN)Cu(I)(Ph~3~As)~2~\]\[PF~6~\] (Ph-BIAN = Bis(phenyl-imino)acenaphthene). \[Cu(NCMe)~4~\]PF~6~ (50 mg, 0.13 mmol) and Ph~3~As (93 mg, 0.30 mmol) was stirred in methylene chloride (10 ml) for 2 h. Ph-BIAN (51 mg, 0.15 mmol) was added and stirring was continued for another 2 h. The product was precipitated with pentane. Slow diffusion of diethyl ether into a methylene chloride solution of the product mixture yielded a dark powder and the title compound as colourless crystals. To identify the colourless crystals a single-crystal analysis was performed.

Refinement {#refinement}
==========

The H-atoms were calculated geometrically and refined using a riding model with C---H = 0.93Å and U(H) = 1.2*U*~eq~(C).

  Experimental. Data were collected applying an imaging plate system (Stoe) with the following measurement parameters:Detector distance \[mm\] 70 Phi movement mode Oscillation Phi incr. \[degrees\] 1.0 Number of exposures 192 Irradiation / exposure \[min\] 2.50For a detailed description of the method see: Sheldrick, G.*M*., Paulus, E. Vertesy, *L*. & Hahn, F. (1995) Acta Cryst. B51, 89--98.
  Geometry. Bond distances, angles *etc*. have been calculated using the rounded fractional coordinates. All su\'s are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.\'s are taken into account in the estimation of distances, angles and torsion angles
  Refinement. Refinement of *F*^2^ against ALL reflections. The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^2^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^2^. The threshold expression of *F*^2^ \> σ(*F*^2^) is used only for calculating *R*-factors(gt) *etc*. and is not relevant to the choice of reflections for refinement. *R*-factors based on *F*^2^ are statistically about twice as large as those based on *F*, and *R*- factors based on ALL data will be even larger.
