[Cu(CH3CN)4](BF4) (0.372 g, 1.0 mmol) was dissolved in CH2Cl2 (15 ml) under nitrogen, and a solution of dppa (0.385 g, 1.0 mmol) and phen (0.18 g, 1.0 mmol) in CH2Cl2 (10 ml) was added at room temperature. The filtrate was kept under a diethyl ether atmosphere for three weeks, during which time yellow block-shaped crystals were formed.
H atoms were placed geometrically and allowed to ride during refinement with C—H = 0.93 Å or 0.97 Å for the CH2Cl2 molecule and with Uiso(H) = 1.2Ueq(C). The tetrafluoroborate anion is modelled as disordered over two orientations with equal site occupancies. All B—F distances were restrained to be 1.38 (1) Å, and the F···F distances within each component were restrained to be equal with an effective standard uncertainty of 0.02 Å (SADI instruction in SHELXL). The C—Cl distances in the CH2Cl2 molecule were restrained to be 1.74 (1) Å.
Diphosphinoamine ligands can bind to metals in monodentate, bidentate, chelating and bridging modes and their complexes find application in diverse areas such as supramolecular design, photophysics and catalysis (Liu et al., 2002; İrişli & Şen, 2005; Ahuja et al., 2007; Sekabunga et al., 2002). The title compound is a new CuI complex with bis(diphenylphosphino)amine (dppa).
The compound consists of [Cu2(phen)2(dppa)2]2+ cations (phen is 1,10-phenanthroline) located on 2-fold rotation axes. The two CuI atoms are bridged by two dppa ligands to form an eight-membered Cu2P4N2 ring. The distance between the two metal centres is 3.616 (4) Å, which is too long for any significant metal–metal bonding interaction. Each CuI atom adopts a distorted tetrahedral coordination geometry, with the angles around CuI ranging from 79.5 (2) ° for N2—Cu1—N3 to 135.28 (5) ° for P1—Cu1—P2A (where the suffix A denotes the symmetry operator -x, y, 1/2 - z).

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. |

Diphosphinoamine ligands can bind to metals in monodentate, bidentate, chelating and bridging modes and their complexes find application in diverse areas such as supramolecular design, photophysics and catalysis (Liu et al., 2002; İrişli & Şen, 2005; Ahuja et al., 2007; Sekabunga et al., 2002). The title compound is a new CuI complex with bis(diphenylphosphino)amine (dppa).
The compound consists of [Cu2(phen)2(dppa)2]2+ cations (phen is 1,10-phenanthroline) located on 2-fold rotation axes. The two CuI atoms are bridged by two dppa ligands to form an eight-membered Cu2P4N2 ring. The distance between the two metal centres is 3.616 (4) Å, which is too long for any significant metal–metal bonding interaction. Each CuI atom adopts a distorted tetrahedral coordination geometry, with the angles around CuI ranging from 79.5 (2) ° for N2—Cu1—N3 to 135.28 (5) ° for P1—Cu1—P2A (where the suffix A denotes the symmetry operator -x, y, 1/2 - z).
