{2-Hydr­oxy-3-[4-(2-methoxy­ethyl)­phen­oxy]prop­yl}isopropyl­ammonium hemisuccinate

Abstract

Metoprolol, a widely used adrenoreceptor blocking drug, is commonly administered as the succinate or tartrate salt. The structure of metoprolol succinate, C15H26NO3 +·0.5C4H4O4 2−, is characterized by the presence of ribbons in which cations, generated by N-protonation of the metoprolol mol­ecules, are hydrogen bonded to succinate anions. The dicarboxylic acid transfers its H atoms to two metoprolol mol­ecules; the asymmetric unit contains one cation and half an anion, the latter possessing twofold rotational symmetry. There are localized nets of O—H(...)O and N—H(...)O hydrogen bonds along a ribbon, within centrosymmetric arrangements formed by pairs of metoprolol cations and pairs of anions, each of the latter contributing with one of its carboxyl groups to the localized net. This arrangement is repeated along the ribbon by the operation of the twofold axis bis­ecting the anion, as well as by the lattice translation.

Comment

Metoprolol, (±)-1-isopropylamino-3-[4-(2-methoxy-ethyl)-phenoxy]- propan-2-ol, is a β1-selective adrenoreceptor blocking drug, widely used in the treatments of hypertension, angina pectoris and heart failure (Benfield et al., 1986; Moses & Borer, 1981; Brogden et al., 1977). The active substance is provided as metoprolol succinate or tartrate for oral administration, available as extended–release tablets (Hainer & Sugg, 2007; Ragnarsson et al., 1987; Sandberg et al., 1988). Although this drug has been in use for some time, a solid-state structure determination was not yet available. Suitable crystals were obtained for the succinate of the active substance.

The structure of metoprolol succinate consists of cations formed by the N–protonated metoprolol molecule and of succinate dianions, in 2:1 ratio. The asymmetric unit (Fig. 1) contains one metoprolol cation and the symmetry–independent part of the succinate anion, the whole anion possessing two–fold rotational symmetry. Disorder affecting the positions of the ether oxygen O3 and of the hydroxyl oxygen O2 was accounted for. The hydrogen atoms were included in geometrically generated positions, although most of them, including the two ammonium H atoms, could be clearly identified in difference Fourier maps. Consistent with a complete deprotonation of the dicarboxylic acid, the lengths of the two carboxylate C—O bonds are similar. That formed by the O4 atom, which participates in two hydrogen bonds (see below), being only slightly larger (by 0.026 (2) Å) than the other one. In the structure, there are ribbons of hydrogen–bonded ions parallel to the c axis (Fig. 2), characterized by the presence of centrosymmetric arrangements where pairs of cations interact with pairs of carboxylate groups belonging to distinct anions. Contiguous arrangements of this type are related to each other along the ribbon by the two–fold rotation axis and two of these contiguous arrangements form the repeat motif in the c direction. There are no hydrogen–bond linkages between the ribbons. In detail, the metoprolol cation forms hydrogen bonds to the two O atoms of a carboxylate group through its hydroxyl group (O2···O4i = 2.723 (2) Å, O2—H2O···O4i = 179.4°; symmetry code (i): x, - y, -1/2 + z) and through an ammonium N—H bond (N···O5i = 2.745 (2) Å, N—H1N···O5i = 162.3°). The same metoprolol cation is furthermore linked to the second anion in the centrosymmetric arrangement along the ribbon, via the other N—H bond (N···O4ii = 2.796 (2) Å, N—H2N···O4ii = 169.7°; symmetry code (ii): 1 - x, y, 3/2 - z). In this way, each metoprolol cation forms hydrogen bonds to two anions and each succinate anion accepts hydrogen bonds from four cations, through its two carboxylate groups. No carbon atom of the phenyl group deviates by more than 0.005 (1) Å from the best plane through the ring and the O1 and C13 atoms deviate respectively by 0.014 (2) Å and 0.009 (2) Å from it. The dihedral angle between the planes through the two parts of the anion, namely atoms O4, O5, C16 and C17 and the symmetry–related ones, is 82.67 (5)° and the torsion angle through the carbon–atoms backbone of the succinate anion is 179.0 (2)°.

Experimental

Samples of metoprolol succinate were kindly provided by SIMS (SIMS srl, Reggello Firenze, Italy). Crystals of the compound, suitable for X-ray diffraction analysis, were obtained by slow evaporation from 3:1 methanol:octanol solutions.

Refinement

Hydrogen atoms were in geometrically generated positions, riding, and the constraint U(H) = 1.2Ueq(C,N) was applied on the hydrogen temperature factors [U(H) = 1.5Ueq(C,O) for the H atoms of the methyl and hydroxyl groups]. It appears that a 2.03 Å H···H contact involving the H2' hydrogen of the disordered hydroxyl group, belonging to the fraction with 0.09 occupancy, whose position was (necessarily) geometrically generated, may be ignored, considering that it would be easily released if the hydroxyl O—H bond were allowed to rotate.

A small number (12) of restraints were employed to ensure that the geometry and displacement parameters of the minor-component disordered atoms maintained chemically reasonable values.

Special details

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 > 2σ(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.
