(Received 13 August 2011; accepted 1 November 2011; online 5 November 2011)

Recently, we reported the first monoclinic [Kuai & Cheng (2011). Acta Cryst., E67, o2787] and the orthorhombic polymorph [Kuai & Cheng (2011). Acta Cryst., E67, o3014] of the title compound, C₁₅H₁₂N₂O₂. Another monoclinic polymorph was obtained accidentally by the hydrothermal reaction of the title compound with manganese chloride in the presence of potassium hydroxide at 413 K. The asymmetric unit consists of four independent molecules. In the crystal, O—H⋯N hydrogen bonds link the independent molecules into four separate chains parallel to the b axis.

Comment top

The title compound, C₁₅H₁₂N₂O₂ (I), is usually regarded as an excellent candidate for building block in molecular self-assembly engineering due to its variable conformation and coordination modes (Das & Bharadwaj, 2009). During assembly of a coordination polymer, we accidentally obtained three polymorphs of (I), which can be proved by different unit-cell parameters and space groups. Here, we are introducing one of them. The single crystals of title compound were accidentally obtained by the hydrothermal reaction of the title compound with manganese chloride and 4,4'-bipyridine as an auxiliary ligand in the presence of potassium hydroxide at 413 K. In the crystal structure, the asymmetric unit consists of four independent molecules (Fig. 1). Hydrogen bonds link every kind of molecules in four separate chains parallel to b axis.(Fig 2).

Experimental top

Reaction mixture of MnCl₂ (21.5 mg, 0.1 mmol), 4-((1H-benzo[d]imidazol-1-yl)methyl)benzoic acid (25.2 mg, 0.1 mmol), 4,4'-bipyridine (15.6 mg, 0.1 mmol) and KOH (5.61 mg, 0.1 mmol) in 10 ml H₂O was sealed in a 16 ml Teflon-lined stainless steel container and heated to 413 K for 3 days. After cooling to the room temperature, colorless block crystals of the title compound were obtained.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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.
