Bis(1,2-diaminobenzene-N)­bis(1,1,1,5,5,5-hexa­fluoro­pen­tane-2,4-dion­ato-O,O')­iron(II), -cobalt(II) and -nickel(II) at low temperature

M. H. Dickman
Addition of 1,2-phenylenediamine to solutions ofbis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-O,O')cobalt(II),-iron(II) and -nickel(II) resulted in crystals containing centrosymmetric octahedral complexes with two amines per metal atom. In all three iso­structural complexes, i.e. [M(C5HF6O2)2(C6H8N2)2] where M = Fe, Cu and Ni, the two C-N bonds differ significantly in length by an average of 0.031 (3) Å. The phenyl C-C bonds display a pattern of small differences, the C-C bond between the amines being longer than the shortest phenyl C-C bonds by an average of 0.022 (4) Å.

Comment top

The title complexes were synthesized in order to explore the coordination of bidentate ligands with M(hfac)2 complexes (hfac is 1,1,1,5,5,5-hexafluoropentane-2,4-dionato-O,O'). Tetramethylethylenediamine and other strong bidentate bases have been observed to coordinate to Fe(hfac)2 in a bidentate fashion to form neutral monomers (Dickman, 1998; Bailey et al., 1981). In contrast, addition of a bidentate nitrone to Fe(hfac)2 resulted in ligand exchange to produce a complex salt (Villamena et al., 1998). The reason for this difference is not clear. 1,2-Phenylenediamine (opda) was chosen for the present study because it is a weaker σ donor than tetramethylethylenediamine. Even when opda was added in a 1:1 ratio to Co(hfac)2, Fe(hfac)2 and Ni(hfac)2 hydrates, only 2:1 amine–metal complexes were isolated from CHCl3/n-heptane solution. The resulting crystal structures show discrete centrosymmetric octahedrally coordinated complexes, with two mondentate opda ligands per metal atom (Fig. 1). The two amine functions on each phenyl ring have different C—N bond lengths. The bond to the metal-coordinated amine, C1—N1, is longer than C2—N2 by 0.031 (3) Å on average. Shortening of the non-coordinated amine function has been seen previously in a monodentate opda complex of bis(1,3-diphenyl-1,3-propanedionato-O,O')nickel(II) [difference of 0.027 (3) Å; Hotz et al., 1987] and in [Cr(opda)2(NCS)2] [difference of 0.059 (3) Å; Jubb et al., 1991]. However, in [Ni(opda)4]2− (Elder et al., 1974) and in a macrocyclic Cd complex (Nelson et al., 1982), monodentate opda showed no significant difference in the C—N bond lengths. Both of these structures had either poor data (e.g. twinning) or larger than usual s.u.'s.

In the present structures, bis(1,2-diaminobenzene-N)bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-O,O')- iron(II), (I), bis(1,2-diaminobenzene-N)bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-O,O')- cobalt(II), (II), and bis(1,2-diaminobenzene-N)bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-O,O')- nickel(II), (III), the N2 NH2 group is slightly more planar than that of N1, as evidenced by the out-of-plane distances of the C atoms bound to the N atoms from the planes of the amines. This value averages 1.07 (4) Å for C2 out of the H1N2—N2—H2N2 plane compared with 1.25 (3) Å for C1 out of the H1N1—N1—H2N1 plane.

The phenyl C—C bond lengths show a pattern of differences not seen in previous structures. The C1—C2 bond, averaging 1.405 (3) Å, is longer by 0.022 (4) Å than the C4—C5 and C5—C6 bonds, which average 1.383 (4) Å. The C2—C3, C5—C6 and C6—C1 bond lengths fall between these values, with an average of 1.393 (4) Å.

A network of apparent intermolecular hydrogen bonds involving H atoms on N1 as donors to N2 and F3 extends through the crystal and an intramolecular hydrogen bond between N2 and O2 is also observed. This intramolecular hydrogen bond, although not especially short, might be one reason that only 2:1 complexes were isolated.

Experimental top

Crystals were grown by addition of stoichiometric amounts of opda to CHCl3 solutions of the appropriate hydrated M(hfac)2 complexes (Morris et al., 1968) with stirring and gentle heating, followed by addition of n-heptane and slow evaporation at room temperature in loosely covered beakers. 19F NMR spectra were measured on a Varian Mercury 300 MHz s pectrometer interfaced with a Sun Microsystems workstation. Spectra were recorded at 294.5 K with CF3COOH in CDCl3 as an external reference. No peak was observed for (I), and peaks for (II) and (III) were observed at 60.79 and 48.40 p.p.m. in CDCl3, respectively. IR spectra were recorded with a Nicolet FT-7000 spectrometer as KBr pellets. The IR spectra were essentially identical for all three compounds, with peaks at (cm−1): 1637 (s), 1600 (m), 1558 (m), 1531 (m), 1506 (m), 1481 (s), 1350 (w), 1261 (s), 1216 (s), 1195 (m), 1151 (s), 1134 (s), 1097 (w), 1074 (m), 1060 (m), 931 (w), 864 (w), 856 (w), 800 (s), 777 (w), 756 (m), 723 (w), 670 (m), 589 (m), 524 (w), 468 (m). Some splitting of peaks was evident in the case of (I), presumably due to oxidation in the pellet press.

Refinement top

For each crystal, decay was monitored by recollection of the first 50 frames at the end of the data collection. H atoms were refined isotropically in observed positions. For all three complexes, final C–H distances ranged from 0.91 (3) to 0.99 (4) Å and final N–H distances ranged from 0.84 (3) to 0.94 (3) Å. In compound (I), the highest peak in the final difference Fourier map was 1.14 Å from F3, for compound (II), it was 1.09 Å from F3, and for compound (III), it was 1.11 Å from F3.

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.

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.
