Abstract top

In the title adduct, 2C18H14N4·C8H6O4, the centrosymmetric 1,4-benzenedicarboxylic acid molecule makes two O-H...·N hydrogen bonds to adjacent 10,11,12,13-tetrahydro-4,5,9,14-tetraazadibenzo[a,c]anthracene (TTBT) molecules. Aromatic [pi]-[pi] stacking interactions occur between TTBT rings [centroid-centroid distance = 3.570 (3) Å], leading to a two-dimensional supramolecular structure in the crystal.

Comment top

Current crystal engineering on the basis of the supramolecular architectures assembled from various noncovalent interactions, such as hydrogen bonds and π-π stacking interactions have been extensively studied owing to their novel topologies and potential applications as functional materials (Stephenson & Hardie, 2006; Yao et al.,2008). 1,10-Phenanthroline (phen) and its derivatives have been widely used to build novel supramolecular architectures (Xu, Li et al., 2008; Che, Liu et al., 2008). As a continuation of our studies in this area, we have prepared the title compound, (I), using the phen derivative 10,11,12,13-tetrahydro-4,5,9,14-tetraazadibenz[a,c]anthracene (TTBA).

The asymmetric unit of (I) consists of one TTBA molecule and half of a centrosymmetric 1,4-benzenedicarboxylic acid molecule (Fig. 1). The two components of (I) interact by way of O—H···N hydrogen bonds (Table 1). Furthermore, there are π-π aromatic stacking interactions involving TTBA ligands of adjacent units [centroid-centroid distance = 3.570 (3)Å], forming an intriguing two-dimensional supramolecular motif (Fig. 2).

Experimental top

The TTBA was synthesized according to the literature method (Che, Li et al., 2006). TTBA (1.0 mmol) and 1,4-benzenedicarboxylic acid (0.5 mmol) were dissolved in aqueous solution and the mixture was sealed in a Teflon-lined autoclave and heated to 433 K for 4 d. Upon cooling and opening the bomb, colorless blocks of (I) were obtained.

Refinement top

The hydrogen atoms were positioned geometrically (C—H = 0.93 Å, O—H = 0.82Å) and refined as riding, with Uiso(H)= 1.2Ueq(carrier).

Special details top

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.
