2-[(Quinolin-8-yl­oxy)meth­yl]-1H-benzimid­a­zole monohydrate

L. Tang, Y. Zhang and Y. Wen

Abstract top

In the title hydrate, C17H13N3O·H2O, the dihedral angle between the quinoline and benzimidazole ring systems is 6.22 (7)°. The water mol­ecule is linked to the main mol­ecule by N-H...O and O-H...N hydrogen bonds. Further O-H...N hydrogen bonds link the organic molecules into C(6) chains running parallel to the b axis.

Comment top

Benzimidazole and 8-hydroxyquinoline and their derivatives find wide application in coordination chemistry (Hanna et al., 2002), pharmaceutical chemistry (Patel et al., 1999; Pierre et al., 2003), and materials chemistry (Liu et al., 2005; Wang et al., 2006). 2-((Quinolin-8-yloxy)methyl)benzimidazole is a tridentate ligand with N2O donor set, and its copper complex exhibited a predominantly ferromagnetic interaction, while its cadmium complex has good fluorescence property (Wen et al., 2011). Here, we report the crystal structure of the title compound.

The title compound consists of a 2-((quinolin-8-yloxy)methyl)benzimidazole molecule and a crystal water molecule (Fig. 1). The whole molecule is essentially planar, with a dihedral angle of 6.22 (7)° between quinoline and benzimidazole ring. The water molecule as donor is hydrogen bonded to N1 atom in quinoline ring and also as acceptor is hydrogen bonded to H2A atom in benzimidazole ring. These two hydrogen bonds (Table 2) viz. O2—H2WB···N1 and N2—H2A···O2 are helpful to the planar structure of the whole molecule. Meanwhile, the water molecule as donor is hydrogen bonded to N3 atom in benzimidazole ring of the neighbouring molecule to form intermolecular hydrogen bond O2—H2WA···N3 [symmetry-code: -x + 1, y + 1/2, -z + 1/2]. So, the crystal structure is stabilized by two intra and and one intermolecular N—H···O ; O—H···N and O—H···N hydrogen bonds respectively, which link the molecules into C(6) chains running parallel to the b axis (Bernstein et al., 1995) (Fig. 2), Table 2.

Experimental top

2-((Quinolin-8-yloxy)methyl)benzimidazole was prepared according to the literature method (Wen et al., 2011). Colourless single crystals of the title compound suitable for X-ray diffraction study were obtained by slow evaporation of an ethanol solution over a period of 15 d.

Refinement top

H atoms were positioned geometrically, with C—H = 0.93–0.98 Å, and constrained to ride on their parent atoms, with Uiso(H) = 1.2 or 1.5 times Ueq of the carrier atoms.

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.
