The title hydrated salt, C16H19FN3O3+·C2H3O2−·1.5H2O, crystallizes with two cations, two anions and three water molecules of crystallization in the asymmetric unit. The protonation of the piperazine secondary amine group of norfloxacin occurs via proton transfer from acetic acid. In the extended structure, the components are linked into chains propagating along the a-axis direction through numerous N—H⋯O and O—H⋯O hydrogen bonds. Hirshfeld surface analysis and two-dimensional fingerprint plots confirm the significant contribution of H⋯O interactions to the consolidation of the crystal structure.
Keywords: crystal structure; norfloxacin; molecular structure; hydrogen bonds.

1. Chemical context
Fluoroquinolones (FQs) are among the most widely used classes of antimicrobial agents, with broad therapeutic applicability in the treatment of respiratory, urinary tract, gastrointestinal, and gynecological infections (Abidi et al., 2016
). Among them, norfloxacin, C16H18FN3O3, is a well-known fluoroquinolone with broad-spectrum antibiotic activity effective against both Gram-positive and Gram-negative bacteria (Grangé et al., 1998
). Structurally, norfloxacin contains a basic piperazinyl nitrogen atom and a carboxylic acid functional group, which contribute to its versatile chemical behavior. In addition to its antibacterial activity, different solid forms of norfloxacin also demonstrate a range of biological properties, including anticancer, antiviral, antioxidant, and antifungal activities (Barry et al., 1984
; Grangé et al., 1998
; Jiang et al., 2025
; Pandeya et al., 2000
; Goldstein, 1987
; Ferrazzi et al., 1988
; Zeng et al., 2024
). Under appropriate conditions, protonation of the piperazinyl nitrogen atom can occur, while the carboxylic acid group may undergo deprotonation, resulting in a zwitterionic form of the molecule. This structural feature also enables norfloxacin to function as an effective ligand in metal complexation (Rasulov et al., 2025
). As part of our studies in this area, we report herein the synthesis and crystal structure of the title hydrated salt, C16H19FN3O3+·C2H3O2−·1.5H2O (I).
2. Structural commentary
Compound (I) crystallizes in the triclinic space group P. The crystal structure analysis reveals that the asymmetric unit comprises two norfloxacin cations (NF), two acetate anions and three water molecules (Fig. 1
). Equivalent atoms in the cations A and B are given suffixes A and B. In neutral norfloxacin, the piperazine N3 nitrogen atom is typically protonated by a hydrogen atom originating from the carboxylic acid group, resulting in the formation of a zwitterionic species (e.g., Gunnam & Nangia, 2023
). However, in the crystal structure of compound (I), the hydrogen atom remains associated with the carboxylic acid moiety, while the N3 nitrogen atom of the piperazine ring is protonated by a proton donated by an acetic acid molecule. This assignment is supported by the significant differences observed in the C—O bond lengths: 0.115 Å between C10A—O1A and C10A—O2A, and 0.12 Å between C10B—O1B and C10B—O2B. In contrast, a delocalized carboxylate group typically exhibits nearly equivalent C—O bond lengths, with differences of approximately 0.006 Å (Rasulov et al., 2024
). This characteristic delocalization is evident in the acetate anions present in the structure, where the C—O bond lengths are nearly identical: 1.244 (3) and 1.242 (3) Å for C17—O4 and C17—O5, respectively, and 1.212 (4) Å for C19—O7 and 1.221 (3) Å for C19—O8. The atoms of both the carboxyl and quinoline moieties are essentially coplanar: the maximum deviations from the mean plane are 0.035 (12) Å for atom C6A in cation A and 0.032 (12) Å for atom C3B in cation B. The dihedral angles between the carboxyl and quinoline planes are 2.00 (12)° for A and 1.46 (12)° for B, indicating near planarity, as expected. The nitrogen atoms N2A and N2B, which are bonded to the quinoline rings, exhibit near-planar geometry, as indicated by the sums of the bond angles around them (353.3 and 353.1°, respectively). In contrast, the protonated nitrogen atoms N3A and N3B display tetrahedral geometries. The piperazine rings in both independent molecules adopt chair conformations. Furthermore, the ethyl substituents attached to atoms N1A and N1B are oriented approximately perpendicular to the quinoline plane, as evidenced by the C1—N1—C11—C12 torsion angles of 94.8 (2) and 94.2 (2)°, respectively. Both cations feature an intramolecular O—H⋯O hydrogen bond.

3. Supramolecular features
The packing of (I), as illustrated in Fig. 2
, reveals that the acetate anions and water molecules occupy interstitial sites between norfloxacinium cations. These species act as bridging units, linking the cations through numerous O—H⋯O and N—H⋯O hydrogen-bonding interactions (Table 1
) into chains propagating along the a-axis direction. Weak C—H⋯O interactions further consolidate the structure. Aromatic π–π stacking interactions, with centroid–centroid separations ranging from 3.5395 (12) to 3.7393 (12) Å, arise from the overlap of aromatic rings of the norfloxacinium moieties.

4. Hirshfeld surface analysis
Hirshfeld surface (HS) analysis and two-dimensional fingerprint plots were calculated using CrystalExplorer (Spackman et al., 2021
). The Hirshfeld surface (HS) of the norfloxacinium cation in (I) exhibits two prominent dark-red spots, indicating the presence of strong close contacts. These interactions are attributed to N–H⋯O hydrogen bonds, specifically between the protonated nitrogen atom and the oxygen atoms of the acetate anion. The two-dimensional fingerprint plots quantify the contributions of various intermolecular contacts to the Hirshfeld surface. The dominant interactions are H⋯H (42.4%), O⋯H/H⋯O (30.1%), C⋯C (9.3%), H⋯F/F⋯H (7.0%), C⋯H/H⋯C (4.1%), and C⋯O/O⋯C (3.1%), which together account for approximately 96.0% of the total surface area of the norfloxacinium cation in (I). The two-dimensional fingerprint plots further reveal that the O⋯H interactions are characterized by a distinct spike at di + de values of approximately 1.7 Å, indicative of strong hydrogen-bonding interactions (Fig. 3
).

5. Database survey
A survey of the Cambridge Structural Database (CSD, Version 6.01, November 2025; Groom et al., 2016
) identified 85 crystal structures based on norfloxacin. Most of these structures incorporate water molecules of crystallisation. Among these, only one structure contains norfloxacin together with both methanol and water (CSD refcode KEBROZ; Wang et al., 2005
). In contrast, six structures include norfloxacin along with additional components and two different types of solvent molecules, namely water in combination with another solvent: three structures contain methanol (KEBGEH, KEBGAD, O'Malley et al., 2022
; KAHWAV, Jiao et al., 2021
), two contain acetonitrile (KEBQOB, O'Malley et al., 2022
; OFOZOC, Zhang et al., 2025
), and one contains ethanol (DONQIK; Zeng et al., 2024
). However, no crystal structure has been reported that contains a norfloxacinium cation, water molecules, and acetate anions simultaneously within the same structure.
6. Synthesis and crystallization
31.9 mg (0.100 mmol) of NF was dissolved in 5 ml of a 0.1 M acetic acid solution. The resulting clear solution was stirred at room temperature for 30 minutes. The solution was then transferred to a vial with small holes in the lid to allow for evaporation. After about a week, block-like single crystals of the title salt were obtained.
7. Refinement
Crystal data, data collection and structure details are summarized in Table 2
. H atoms were positioned geometrically (N—H = 0.89, O—H =0.82– 0.85, C—H = 0.93–0.97 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
