Abstract top

The organic cation of the title salt, C17H12N4O2+·2Cl-·H2O, is nearly planar, the dihedral angle between two pyridine rings being 2.53 (16)° and that between the pyridinum and furan rings being 4.17 (19)°. Molecules are linked via N-H...O, N-H...Cl and O-H...Cl hydrogen bonds, forming a three-dimensional framework and [pi]-[pi] stacking interactions help to stabilize the crystal structure [the imidazole-pyridine and imidazole-benzene centroid-centroid distances are 3.501 (3) and 3.674 (3) Å; respectively].

Comment top

Recent year, we used different alkyl-substituted glycolurils as the building blocks to synthesize the partially alkyl substituted cucurbit[n]urils (Zhao et al., 2004; Zheng et al., 2005). In this work, we further report the crystal structure of a phenanthroline-substituted semi-glycoluril.

The molecular structure of the title compound (I), consists of organic cations, two Cl- anions and one water molecule (Fig. 1). The organic cation is nearly planar, the dihedral angle between two pyridine rings is 2.53 (16) ° and that one between N4-pyridine ring and furan ring is 4.17 (19)°. Molecules are linked via N1—H1A···O1W, N2—H2A···Cl1, N4—H4···Cl2, O1W—H1WA···Cl2 and O1W—H1WB···Cl2 hydrogen bonds (Table 1) forming a three-dimensional framework. In additional, the π···π stacking interaction occurs between adjacent organic cations, the centroid-to-centroid distance of Cg2 to Cg3iv is 3.501 (3)Å and Cg2 to Cg5iv is 3.674 (3)Å [Cg2, Cg3 and Cg5 is the centroid of the N1-imidazole ring, N3-pyridine ring and C6-benzene ring, respectively. Symmerty codes: (iv) -1 + x, y, z].

Experimental top

1,10-Phenanthroline-5,6-dione (1.0 g, 4.75 mmol) and ammonium acetate (3.9 g, 5 mmol) are dissolved in acetic acid glacial (60 mL) at 333 K, after cooling at room temperature, we can get lots of yellow deposits by the neutrlizing with ammonia to pH = 8–9 after 4 h of mixing with furaldhyde (0.8 mL) at 353 K. After the recryslalization in ethanol, the yellow product was dissolved in the dilute hydrochloric acid and red-brown crystals were obtained

after ten days.

Refinement top

Water H atoms were located in a difference Fourier synthesis and refined riding in their as-found positions relative to O atoms with Uiso(H) =1.2Ueq(O). All other H atoms were placed in calculated positions and refined as riding, with C—H = 0.93–0.97 Å, N—H = 0.86 Å, and with Uiso(H) = 1.2 Ueq (C, N).

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.
