The structures of two pseudopolymorphic hydrates of brucine, C23H26N2O4·4H2O, (I), and C23H26N2O4·5.25H2O, (II), have been determined at 130 K. In both (I) and (II) (which has two independent brucine molecules together with 10.5 water molecules of solvation in the asymmetric unit), the brucine molecules form head-to-tail sheet substructures, which associate with the water molecules in the interstitial cavities through hydrogen-bonding associations and, together with water-water associations, give three-dimensional framework structures.

Brucine tetrahydrate, (I), was obtained as isolated clusters of well formed colourless prismatic needles [m.p. 378 K (literature) (Moffat, 1986; Buckingham, 1982)] from the attempted preparation of a brucine–adenosine adduct in 50% ethanol–water, after partial room-temperature evaporation. Hydrate (II) was obtained from an attempted preparation of a brucine–urea adduct in 50% ethanol–water, as large colourless prismatic crystals (m.p. 386.9–388.2 K).
H atoms potentially involved in hydrogen-bonding interactions were generally located by difference methods. However, a number of the H atoms of the water molecules of (II) could not be located and were included in the refinement at calculated sites dictated by the assumed hydrogen-bonding geometry. Because of the low reflection/refined parameter ratio, all water H atoms were constrained in the refinement. Brucine H atoms were included at calculated positions [C—H(aromatic) = 0.95 Å; C—H(aliphatic) = 0.96–0.99 Å] and treated as riding, with Uiso(H) values of 1.2Ueq(C), or 1.5Ueq(C) for methyl atoms. The atom-numbering scheme for brucine (Figs. 1 and 3) follows the original Robinson convention used for strychnine (Holmes, 1952). The absolute configuration determined for the parent strychnine (Peerdeman, 1956) was invoked.
For both compounds, data collection: SMART (Bruker, 2000); cell refinement: SMART; data reduction: SAINT (Bruker, 1999). Program(s) used to solve structure: SHELXTL?? (Bruker, 1997) and WinGX (Farrugia, 1999) for (I); SHELXS97 (Sheldrick, 1997) and WinGX (Farrugia, 1999) for (II). Program(s) used to refine structure: SHELXTL?? and WinGX for (I); SHELXL97 (Sheldrick, 1997) and WinGX for (II). For both compounds, molecular graphics: PLATON (Spek, 2003); software used to prepare material for publication: PLATON.

Special details top
Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All e.s.d.'s are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

Special details top
Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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 commercially available form of the alkaloid brucine is a tetrahydrate, this being first reported by Groth (1919). The crystal structure of the anhydrous form (m.p. 451 K), readily obtained from the hydrate by heating at 373 K (O'Neil, 2001), has been reported recently (Bialońska & Ciunik, 2004a). Although the crystal cell data for the orthorhombic tetrahydrate have been reported (Eeles, 1953), its structure has not previously been determined. Reported along with the anhydrous brucine structure were the structures of two brucine solvate pseudopolymorphs (Bernstein, 1987; Kumar et al., 1999), brucine acetone solvate and brucine 2-propanol solvate dihydrate (Bialońska & Ciunik, 2004a). This 2-propanol solvate structure is isomorphous with the previously reported brucine ethanol solvate dihydrate structure (Glover et al., 1985). Molecular recognition has been demonstrated as being significant in dictating the selectivity shown by brucine for various molecules, including the classic Fischer-type resolved N-benzoyl-protected alanine enantiomers (Fischer, 1899; Gould & Walkinshaw, 1984) and the compound with an achiral molecule, brucinium 3-nitrobenzoate (Oshikawa et al., 2002), where no crystalline products were obtained with the ortho- or para-substituted benzoic acid isomers. With the brucine compounds generally, the brucine species commonly form regular undulating parallel or antiparallel host sheet substructures built from partially overlapping head-to-tail molecular associations (Gould & Walkinshaw, 1984; Dijksma, Gould, Parsons, Taylor & Walkinshaw, 1998; Bialońska & Ciunik, 2004b). The compatible guest species then may occupy the interstitial cavities, associating with the host sheets through hydrogen-bonding interactions. Molecules of solvation (commonly water) act in either a proton-donor/acceptor or a space-filling capacity.
The tetrahydrate, (I), obtained as minor clusters of well formed prismatic needles from the attempted preparation of a brucine–adenosine adduct in 50% ethanol–water, was confirmed from the cell parameters and space group as being the orthorhombic tetrahydrate reported by Eeles (1953) (a = 7.6 Å, b = 11.6 Å, c = 26.6 Å, Z = 4, space group P212121). The second pseudopolymorphic hydrate, brucine 5.25-hydrate, (II), was similarly obtained, but in good yield, in an attempted preparation of a brucine–urea adduct in 50% ethanol–water. Initial diffraction data for (II), obtained at room temperature on a conventional four-circle diffractometer, provided a structure having an asymmetric unit comprising two ordered brucine molecules and 11 water molecules of solvation with varying occupancies in a centred monoclinic cell. The occupancies varied from ca 0.3–0.9, indicating significant solvate lability, although negligible crystal decay was evident from the intensity-standards change (0.25%) during the data collection period. This lability has also been observed in a number of recently determined brucine structures (Gould et al., 2002; Bialońska et al., 2005; Smith, Wermuth, Healy et al., 2005; Smith, Wermuth & White, 2005). Low-temperature [130 (2) K] data were therefore re-collected for (II), and later for (I), using a CCD-detector-equipped diffractometer, effectively resolving the problem.
The atom-numbering scheme for (I) is shown in Fig. 1, while Fig. 3 shows the presence of two independent brucine molecules (A and B) and 11 water molecules of solvation (one with an occupancy of 0.5) in the molecular repeating unit of (II). In addition, one of the water molecules in (II) is disordered over two approximately equal close sites [O10W with occupancy factor 0.543 (17), and O11W with occupancy factor 0.457 (17)]. The atom numbering for the brucine species in both (I) and (II) follows the original Robinson convention (Holmes, 1952) and both have the overall Cahn–Ingold–Prelog absolute configuration for the neutral brucine molecule (Eliel, 1962) [C7(R), C8(S), C12(S), C13(R), C14(R), C16(S)]. As expected, the rigid brucine molecules show negligible conformational variation, including the methoxy substituent groups, which are invariably anti-related and lie essentially in the plane of the benzene ring.
The brucine molecules in (I) form into the previously described undulating sheet substructures, which extend through the crystal along the b cell direction (Fig. 2). These are generated by the 21 screw operation along the c axis giving antiparallel sheet propagation along b, with a dimeric repeat in that direction of 11.53 Å (the a cell dimension). This value is significantly shorter than the common repeat of ca 12.5 Å found in a number of brucine structures, e.g. brucinium N-benzoylalinate–water (1/4.5) (antiparallel, 12.42 Å) (Gould & Walkinshaw, 1984); brucinium D-glucuronate trihydrate (parallel, 12.66 Å) and brucinium D-galacturonate monohydrate (antiparallel, 12.37 Å) (Dijksma, Gould, Parsons & Walkinshaw, 1998); the two brucinium cyanohydrin complexes (both antiparallel, 12.39 and 12.52 Å; Pinkerton et al., 1993), brucine 2-propanol solvate dihydrate (antiparallel, 12.37 Å; Biolońska & Ciunik, 2004a); and brucine ethanol solvate dihydrate (antiparallel, 12.34 Å; Glover et al., 1985). This shortening of the repeat interval parallels a contraction of the angle α [ca 87 ° in (I) but typically greater than 100°] between the lines drawn down the centre of the indole rings of adjacent brucine molecules in the head-to-tail interactive sequence (see Fig. 2).
In (II), the brucine substructure generated by the two independent molecules in the asymmetric unit differs significantly from that seen in (I) (Fig. 4). However, if the B molecules alone are considered, these do form into similar undulating sheet structures, which extend along the b cell direction with an approximate 12.2 Å dimer repeat (Fig. 5). In both (I) and (II), the intersheet cavities generated accommodate the water molecules of solvation, the overall structures being characterized by extensive hydrogen-bonding interactions (Tables 1 and 2). These involve all available proton donors and acceptors in water–brucine [both N19 and O25 (carbonyl) acceptors] and water–water interactions. In addition, there are unusual (for brucine) water–O(cage ether) interactions in both structures, viz. O4W—H···O24iii [symmetry code; (iii) x + 1, y, z {sym code iv in Table 2?}] in (I) and O10W—H···O24Avi [symmetry code; (vi) −x + 1, y, −z + 1] in (II). Additionally, in (II), there are water–O(methoxy) interactions, viz. O7W—H···O2B,O3B (symmetrical three-centred) and O9W—H···O3A (linear), also unusual for brucine and its compounds. In both pseudopolymorphs, three-dimensional framework structures are generated.
In the structure of (II), the molecular asymmetric unit comprises two brucine molecules and 11 water molecules [one of which (O12W) has half-occupancy], together with the previously mentioned, approximately equal, partially occupying disordered molecules O10W [0.543 (17)] and O11W [0.457 (17)]. The observation with (II) that there was no apparent physical crystal deterioration during the room-temperature conventional diffractometer data collection period indicates the stability of the basic brucine substructure, which is retained with some variation in the structure of the anhydrous form (Bialońska & Ciunik, 2004a) (where there are no interstitial species, hence only intersheet interactions), resulting in a larger angle (ca 123 °) between adjacent brucine molecules in the parallel-mode substructure. This gives a longer dimer repeat (12.7 Å), and compares with ca 115° in the N-benzoylalinate salt, ca 110° in the 2-propanol hydrate structure and ca 113° for the B-molecule chains in (II).
