1-[(3RS,4RS)-1-Benzyl-4-methyl-piperi-din-3-yl]-1,6-dihydro-imidazo[4,5-d]pyrrolo-[2,3-b]pyridine hemihydrate.

The benzyl residue in the title compound, C(21)H(23)N(5)·0.5H(2)O, is oriented at a dihedral angle of 83.8 (3)° towards the 1,6-dihydro-imidazo[4,5-d]pyrrolo-[2,3-b]pyridine system. The piperidine ring adopts a chair conformation with the cis substituents displaying a torsion angle of -45.91 (16)°. In the crystal, mol-ecules are accumulated as racemic dimers by two inter-molecular hydrogen bonds between the pyrrolo-pyridine systems. Another hydrogen bond is formed between the imidazole ring and the cocrystallized water mol-ecule, which is located on a twofold rotation axis.

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.
