(Tetra­hydro­borato)bis­(tri­phenyl­phosphine)copper(I): a redetermination at 90 K

The structure of the title compound, [Cu(PPh₃)₂(BH₄)], has been redetermined at 90 K. The geometric parameters of the present structure agree with those previously studied at room temperature [Lippard & Melmed (1967). Inorg. Chem. 6, 2223-2228; Li et al. (2000). Chin. J. Struct. Chem. 19, 91-94], but with significantly improved precision. The molecule has twofold rotation symmetry.
