Reaction of N,N′-(cyclo­hexane-1,2-diyl­idene)bis­(4-fluoro­benzo­hydrazide), C20H18F2N4O2, (LF), with zinc chloride and mercury(II) chloride produced different types and shapes of neutral coordination com­plexes, namely, di­chlorido­[N,N′-(cyclo­hexane-1,2-diyl­idene)bis­(4-fluoro­benzo­hydrazide)-κ2N,O]zinc(II), [ZnCl2(C20H18F2N4O2)], (1), and di­chlorido­[N,N′-(cyclo­hexane-1,2-diyl­idene)bis­(4-fluoro­benzo­hydrazide)-κ4O,N,N′,O′]mercury(II), [HgCl2(C20H18F2N4O2)], (2). The organic ligand and its metal com­plexes are char­acterized using various techniques: IR, UV–Vis and nuclear magnetic resonance (NMR) spectroscopies, in addition to powder X-ray diffraction (PXRD), single-crystal X-ray crystallography and microelemental analysis. Depending upon the data from these analyses and measurements, a typical tetra­hedral geometry was confirmed for zinc com­plex (1), in which the ZnII atom is located outside the bis­(benz­hydrazone) core. The HgII atom in (2) is found within the core and has a common octa­hedral structure. The in vitro anti­bacterial activities of the prepared com­pounds were evaluated against two different bacterial strains, i.e. gram positive Bacillus subtilis and gram negative Pseudomonas aeruginosa bacteria. The prepared com­pounds exhibited differentiated growth-inhibitory activities against these two bacterial strains based on the difference in their lipophilic nature and structural features.

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.

Refinement. STOE diffractometer equipped with an IPDS II image plate detector was used to collect the crystal data of LF, 1 and 2. The collection was carried out at room temperature (296K) using graphite monochromated Mo Kα radiation (λ=0.71073Å) inω-scanning mode. SHELXS-97(Sheldrick, 1997)was used to solve (direct methods) and refine (full-matrix least-squares method) the structures, implemented in the WinGX (Farrugia, 1999)program suite.

Data collection: X-AREA and data reduction: X-RED32 (Cie, 2002). All non-hydrogen atoms were assigned anisotropic thermal parameters. Experimental details of the crystal data, data collection and refinement are illustrated inTable 1. The structure analysis and presentation of the results were done by the general-purpose crystallographic tool PLATON(Spek, 2009), while themolecular graphics were made by ORTEP-3 for Windows(Farrugia, 1997).

Special details top

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.

Refinement. Refined as a 2-component twin.

STOE diffractometer equipped with an IPDS II image plate detector was used to collect the crystal data of LF, 1 and 2. The collection was carried out at room temperature (296K) using graphite monochromated Mo Kα radiation (λ=0.71073Å) inω-scanning mode. SHELXS-97(Sheldrick, 1997)was used to solve (direct methods) and refine (full-matrix least-squares method) the structures, implemented in the WinGX (Farrugia, 1999)program suite.

Data collection: X-AREA and data reduction: X-RED32 (Cie, 2002). All non-hydrogen atoms were assigned anisotropic thermal parameters. Experimental details of the crystal data, data collection and refinement are illustrated inTable 1. The structure analysis and presentation of the results were done by the general-purpose crystallographic tool PLATON(Spek, 2009), while themolecular graphics were made by ORTEP-3 for Windows(Farrugia, 1997).

Special details top

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.

Refinement. STOE diffractometer equipped with an IPDS II image plate detector was used to collect the crystal data of LF, 1 and 2. The collection was carried out at room temperature (296K) using graphite monochromated Mo Kα radiation (λ=0.71073Å) inω-scanning mode. SHELXS-97(Sheldrick, 1997)was used to solve (direct methods) and refine (full-matrix least-squares method) the structures, implemented in the WinGX (Farrugia, 1999)program suite.

Data collection: X-AREA and data reduction: X-RED32 (Cie, 2002). All non-hydrogen atoms were assigned anisotropic thermal parameters. Experimental details of the crystal data, data collection and refinement are illustrated inTable 1. The structure analysis and presentation of the results were done by the general-purpose crystallographic tool PLATON(Spek, 2009), while themolecular graphics were made by ORTEP-3 for Windows(Farrugia, 1997).
