Tris(2,2'-bipyridine-[kappa]2N,N')copper(II) bis(tetrafluoridoborate)

W. Huang

Abstract top

The Cu atom in the title salt, [Cu(C10H8N2)3](BF4)2, has an elongated octahedral coordination geometry. Three F atoms of one anion are disordered over two positions with a site occupancy ratio of 3:2.

Comment top

The crystal structure of tris(2,2'-bipyridine)copper diperchlorate (Anderson, 1972; Liu et al., 1991; Majumdar et al., 1998; Pavlishchuk et al., 1999) and tris(2,2'-bipyridine)copper bis(tetraphenylborate) (Murphy et al., 2006) have been reported previously. We have reported the bis(hexafluoridophosphorate) salt (Wang et al., 2007), and continue our work with the bis(tetrafluoridoborate) salt.

The geometry of the copper atom is an elongated octahedron as the structure has four nearly identical Cu–N bonds and two somewhat longer ones that are trans to each other. The three 2,2'-bipyridine rings are bent, with dihedral angles of 11.2 (3)° (between C1 to C5 and N1 ring and C6 to C10 N2 ring), 31.0 (3)° (between C11 to C15 and N3 ring and C16 to C20 N4 ring) and 14.6 (3)° (between C21 to C25 and N5 ring and C26 to C30 N6 ring).

Experimental top

The compound was obtained by refluxing Cu(NO3)2·3H2O (0.121 g, 0.5 mmol) and 2,2'-bipyridine (0.234 g, 1.5 mmol) in a mixture of 80 ml e thanol and 20 ml water for 1 h in the presence of excess NaBF4. The mixture was concentrated to nearly 5 ml. The blue product was recrystallized from a 3/1 methanol water mixture and the pure compound isolated in 90% yield. CH&N elemental analysis. Calculated for C30H24CuN6F12P2: C 51.06, H 3.43, N 11.91%; found: C 51.04, H 3.49, N 11.86%.

Refinement top

The non-hydrogen atoms were refined anisotropically, whereas the H atoms were placed in geometrically idealized positions (C—H = 0.93 Å) and refined as riding atoms, with Uiso(H) = 1.2Ueq(C). F5, F6 and F7 atoms of one tetrafluoridoborate anion are refined over two sites with 0.60 (2): 0.40 (2) site occupancy factors.

Special details top

Experimental. The structure was solved by direct methods (Bruker, 2000) and successive difference Fourier syntheses.

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.
