In the title compound, C27H31FN2O2+·2Cl−·H2O, the piperazine ring adopts a chair conformation and both N atoms are protonated. The Cl− anions form strong hydrogen bonds to these protons. O/N—H⋯Cl and C—H⋯O hydrogen bonds link the anions, cations and water of hydration into a three-dimensional network.

The 1-diphenylmethyl-4-[3-(4-fluorobenzoyl)propyl]piperazine base was synthesized according to a reported procedure (Wang et al., 2003). The title compound was prepared by passing dry hydrochloride gas (100 mg) through a solution of 200 mg base in ethanol (2 ml). The single-crystals of the title compound suitable for X-ray analysis were obtained by vapor diffusion in a solution of chloroform in which the compound was soluble by benzene acting as anti-solvent.
The H atoms were placed at calculated positions in the riding model approximation with N—H = 0.91 Å and C—H = 0.93, 0.97 and 0.98 Å, for aryl, methylene and methyne type H-atoms, respectively, with Uiso(H) = 1.2 Ueq(C/N). H atoms of water molecule were located in difference Fourier maps and were refined freely with isotropic displacement parameters.
The
of 1-diphenylmethyl-4-[3-(4-fluorobenzoyl)propyl]piperazine has been reported (Zhou & Jin, 1986). In this article we report the structure of its dihydrochloride monohydrate.In the title compound (Fig. 1), the piperazine ring adopts a chair conformation with the piperizine-N atoms protonated. The Cl- anions form strong halogen hydrogen bonds to these protons. Two chlorine ions and one hydrone bridge piperazine cations through the O—H···Cl and N—H···Cl halogen hydrogen bonds result in a one-dimensional chain structure. Moreover, these hydrogen bonds, as well as C═O···H hydrogen bonds (Table 1), link the molecular moieties into a two dimensional sheet in the b-c plane. The water of hydration further consolidates the structure via hydrogen bonds of the type O—H···C. Overall, the individual molecule packs together into a three-dimensional network with a spiral structure motif (Fig. 2).

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. |

The crystal structure of 1-diphenylmethyl-4-[3-(4-fluorobenzoyl)propyl]piperazine has been reported (Zhou & Jin, 1986). In this article we report the structure of its dihydrochloride monohydrate.
In the title compound (Fig. 1), the piperazine ring adopts a chair conformation with the piperizine-N atoms protonated. The Cl- anions form strong halogen hydrogen bonds to these protons. Two chlorine ions and one hydrone bridge piperazine cations through the O—H···Cl and N—H···Cl halogen hydrogen bonds result in a one-dimensional chain structure. Moreover, these hydrogen bonds, as well as C═O···H hydrogen bonds (Table 1), link the molecular moieties into a two dimensional sheet in the b-c plane. The water of hydration further consolidates the structure via hydrogen bonds of the type O—H···C. Overall, the individual molecule packs together into a three-dimensional network with a spiral structure motif (Fig. 2).
