(Received 7 December 2005; accepted 12 January 2006; online 27 January 2006)

The crystal structure of ampicillin trihydrate {systematic name: 6-[D(−)-α-amino­phenyl­acetamido]penicillanic acid trihydrate}, C16H19N3O4S·3H2O, a broad-spectrum β-lactam anti­biotic of the amino­penicillin type, has been determined from synchrotron X-ray powder diffraction data. The three water molecules form an infinite hydrogen-bonded chain through the crystal structure, with hydrogen bonds to the NH3+, COO−, C=O and NH groups of the ampicillin molecules.

Comment

The title compound, (I)[link], has been used as a broad-spectrum anti­biotic since 1961. The crystal structure was reported in 1968 (James et al., 1968[James, M. N. G., Hall, D. & Hodgkin, D. C. (1968). Nature, 220, 168-170.]), but no atomic coordinates were given in the paper or deposited. Boles et al. (1978[Boles, M. O., Girven, R. J. & Gane, P. A. C. (1978). Acta Cryst. B34, 461-466.]) published the crystal structure of a related compound, amoxycillin tri­hydrate. They apparently had access to the atomic coordinates of the crystal structure of compound (I)[link], because in their paper they show that the two crystal structures are isostructural. However, the atomic coordinates of the title compound have not been published to date. We report the crystal structure here, determined from synchrotron X-ray powder diffraction.

[Scheme 1]

The structural model of compound (I)[link] obtained in the present work (Fig. 1[link]a) is both chemically reasonable and in accord with the figures given by James et al. (1968[James, M. N. G., Hall, D. & Hodgkin, D. C. (1968). Nature, 220, 168-170.]). Selected geometric parameters are given in Table 1[link]. We note, however, that the hydrogen bond O26′′′⋯O25′′′ in their Fig. 1[link], which appears to link four water mol­ecules together into a closed tetra­mer, is spurious, and instead should have formed a chain (Fig. 1[link]b). Both the pattern of hydrogen bonding, and the positions of the H atoms of the water mol­ecules in the structure, are chemically sensible and compare well with those from the crystal structure of the isostructural amoxycillin trihydrate (Boles et al., 1978[Boles, M. O., Girven, R. J. & Gane, P. A. C. (1978). Acta Cryst. B34, 461-466.]). Details of the O—H⋯O and N—H⋯O hydrogen bonds are given in Table 2[link] and Fig. 1[link].

Experimental

The sample of compound (I)[link] was a gift from Setauket Pharmacy, Setauket, New York, USA, in the form of a gelatin capsule of the compound. Some of the contents were loaded into a thin-walled glass capillary of 1.5 mm nominal diameter. Any excipients that might have been present were not crystalline. A diffraction pattern was collected at the X3B1 beamline of the National Synchrotron Light Source, Brookhaven National Laboratory. The wavelength of 0.7003 (1) Å was selected by a double Si(111) monochromator and the diffracted beam analyzed by a Ge(111) crystal before the detector. The beam on the sample had dimensions 2 mm × 8 mm. Data were collected from 2θ = 3–41.6° in steps of 0.005°, with counting time increasing quadratically from 1–8 s per point. The incident beam was monitored by an ion chamber, which was used to normalize the data for decay and fluctuations of the intensity.

The starting model for Rietveld refinement was obtained by solving the crystal structure from the powder diffraction pattern. This also provided an independent check that the published crystal structure is correct. However, with the crystal structure being known, its determination from the powder pattern is mainly academic. The crystal structure was determined with the program DASH (David et al., 2004[David, W. I. F., Shankland, K., Van de Streek, J., Pidcock, E. & Motherwell, S. (2004). DASH. Version 3.0. Cambridge Crystallographic Data Centre, 12 Union Road, Cambridge, England..]). For the structure solution, the data were truncated at 22.855° in 2θ, corresponding to a real-space resolution of 1.767 Å. The background was subtracted with a Bayesian high-pass filter (David & Sivia, 2001[David, W. I. F. & Sivia, D. S. (2001). J. Appl. Cryst. 34, 318-324.]). Peak positions for indexing were obtained by fitting with an asymmetry-corrected Voigt function, followed by indexing with the program DICVOL (Boultif & Louer, 1991[Boultif, A. & Louer, D. (1991). J. Appl. Cryst. 24, 987-993.]). An ortho­rhom­bic and several monoclinic unit cells were obtained. However, all the monoclinic unit cells were pseudo-ortho­rhom­bic with nearly the same parameters as the ortho­rhom­bic cell, indicating that the ortho­rhom­bic unit cell is the correct one. The figures of merit given by DICVOL were M(20) = 62.1 and F(20) = 337.1 (0.0014, 42). The space group reported for the single-crystal structure, P212121, gave an excellent Pawley fit.

Simulated annealing was used to solve the crystal structure of compound (I)[link] from the powder pattern in direct space. The starting mol­ecular geometry was taken from the anhydrate (Boles & Girven, 1976[Boles, M. O. & Girven, R. J. (1976). Acta Cryst. B32, 2279-2284.]), entry AMCILL in the Cambridge Structural Database (Allen, 2002[Allen, F. H. (2002). Acta Cryst. B58, 380-388.]). The mol­ecule is a zwitterion, in agreement with the single-crystal study. Because H atoms do not contribute significantly to the powder diffraction pattern, due to their low X-ray scattering power, they were ignored during the structure solution process. Hence, the water mol­ecule can be reduced to an O atom, which reduces its number of degrees of freedom from six to three. The mol­ecule has five flexible torsion angles, which, when combined with the three water mol­ecules, give a total of 20 degrees of freedom. In ten simulated annealing runs, the correct crystal structure was found twice, with a profile χ2 = 81.7, 11 times the Pawley χ2. The next-best crystal structure had a profile χ2 = 240. The low success rate and high profile χ2 are caused by the high R factor of 10.6% of the crystal structure of AMCILL from which the starting model was taken; when the structure solution was repeated with a better starting model (obtained from Rietveld refinement against the powder data), the correct structure was found four times in ten runs, with a profile χ2 = 20, less than three times the Pawley χ2.

The background subtraction, peak fitting, indexing, Pawley refinement and simulated-annealing algorithms used are as implemented in the program DASH.

For the Rietveld refinement (Fig. 2[link]), H atoms were included in the initial model in calculated positions. Bond lengths, bond angles and planar groupings were subjected to suitable constraints, including bonds to H atoms. Data were included to 41.42° in 2θ, corresponding to a real-space resolution of 0.99 Å. The refinement was not particularly sensitive to the position of the water H atoms and these were included in calculated positions, with the water mol­ecules being fixed in position for the final refinement cycles. The refinement proceeded smoothly to reach a minimum characterized by an excellent fit to the diffraction profile (χ2 = 5.637, Rp = 0.0296, Rwp = 0.0296 and RBragg = 0.0295).
