The title compound (Hbpbp), C36H40N6O, is a phenol with one intramolecular bifurcated hydrogen bond. This result furnishes an explanation as to why the otherwise symmetric deprotonated ligand shows a propensity for forming asymmetric, e.g. heterovalent and heterometallic, coordination compounds.

Comment top

We have used the phenolate-hinged dinucleating ligand bpbp for the synthesis of dimetallic coordination compounds and have succeeded in crystallizing the parent phenol, Hbpbp, (I). This together with the dichloride diperchlorate tetraprotonated double salt of H5bpbp4+ (Gomez et al., 2000) has given us further insight in the mechanism of the ligand coordination.

The conformation of (I) (Fig. 1) is dominated by an intramolecular bifurcated hydrogen bond from the phenol O1—H1 group to N2 [2.11 (2) Å] of one arm and N221 [2.43 (2) Å] of one pyridine of that same arm. The angles around H1 sum to 255 (3)°. This hydrogen bond gives a C1—C2—C20—N2 torsion angle of −47.7 (3)° (syn). The C1—C6—C60—N6 torsion angle on the other hand is 174.48 (17)° (anti). This can be explained by a 2.53 Å hydrogen bond from C5—H5 of the phenol ring to N6 of the other ligand arm. In addition, atoms H613 and H623 of the attached pyridine rings form similar hydrogen bonds to N6 (2.53 and 2.55 Å, respectively). In the previously investigated H5bpbp4+ cation, these C—H donors have been displaced by N—H donors from the protonated pyridines. As a result, both amines are oriented syn to the O—H group.

The molecular packing is dominated by C—H···N [shortest contacts 2.61 Å for H8a···N621i and H626···N611ii; symmetry codes: (i): 1 + x, y, 1 + z; (ii) x, y, −1 + z] and C—H···π bonding [shortest contacts are to the central phenol ring (centroid = PC): H216···PCiii = 2.85 Å and H224···PCiv; symmetry codes: (iii) −1/2 + x, 1/2 − y, 1/2 + z; (iv) 1/2 + x, 1/2 − y, −1/2 + z].

We propose that the asymmetry between the bis(pyridin-2-ylmethyl)aminomethyl arms, one hydrogen-bonded, one dangling, can account for the observed asymmetric coordination chemistry of the bpbp ligand (Ghiladi et al., 1997, 1999). A stepwise insertion of two metal ions seems likely because the dangling arm is more available for coordination.

Experimental top

Compound (I) was synthesized according to a published procedure (Ghiladi et al., 1997). The raw product was subjected to column chromatography with acetone as eluent. Prismatic crystals suitable for diffraction were formed by subsequent recrystallization from acetone.

Refinement top

All H atoms could be located from a Fourier difference map. The phenol proton was refined isotropically in the riding mode, with Uiso(H1) = 1.2Ueq(O1) and the bond length O1—H1 restrained to 0.90 (5) Å. The remaining ligand H atoms were constrained to ideal positions with Uiso = 1.2Ueq(parent atom).

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.
