Single crystals of the title complex, [Zn(C7H5N2O4)2(C2H6OS)2] or [Zn(NBZH)2(DMSO)2], were isolated from a dimethyl sulfoxide (DMSO) solution containing [Zn(NBZH)2]·2H2O (NBZH = 3-nitro­benzo­hydroxamate anion). The asymmetric unit comprises of one O,O′-chelating NBZH anion, one O-bound DMSO ligand and one zinc(II) cation localized on an inversion centre. The three-dimensional crystal packing includes N—H⋯O and C—H⋯O hydrogen bonding, as well as O⋯H and H⋯H contacts identified by Hirshfeld isosurface analysis.

Structure description

Hydroxamic acids, RC(=O)–NH–OH (where R = alkyl, ar­yl), play important roles in biology and medicine and have been a source of great inter­est because they present a wide variety of biological activities (Codd, 2008[Codd, R. (2008). Coord. Chem. Rev. 252, 1387-1408.]; Marmion et al., 2004[Marmion, C. J., Griffith, D. & Nolan, K. B. (2004). Eur. J. Inorg. Chem. 2004, 3003-3016.]). These are related to the ability to form stable complexes with metal ions, especially iron(III) (Ugwu et al., 2014[Ugwu, D. I., Ezema, B. E., Eze, F. U., Ayogu, J. I., Ezema, C. G. & Ugwuja, D. I. (2014). Am. J. Org. Chem. 4, 26-51.]; Griffith et al., 2008[Griffith, D., Krot, K., Comiskey, J., Nolan, K. B. & Marmion, C. J. (2008). Dalton Trans. pp. 137-147.]). In addition, this class of compounds provides several sites for hydrogen-bonding inter­actions with enzyme structures, thus becoming potent and selective inhibitors of a number of enzymes such as matrix metalloproteinase (Muri et al., 2002[Muri, E. M. F., Nieto, M. J., Sindelar, R. D. & Williamson, J. S. (2002). Curr. Med. Chem. 9, 1631-1653.]; Sani et al., 2004[Sani, M., Belotti, D., Giavazzi, R., Panzeri, W., Volonterio, A. & Zanda, M. (2004). Tetrahedron Lett. 45, 1611-1615.]), peroxidases (O'Brien et al., 2000[O'Brien, E. C., Farkas, E., Gil, M. J., Fitzgerald, D., Castineras, A. & Nolan, K. B. (2000). J. Inorg. Biochem. 79, 47-51.]; Indiani et al., 2003[Indiani, C., Santoni, E., Becucci, B., Boffi, A., Fukuyama, K. & Smulevich, G. (2003). Biochemistry, 42, 14066-14074.]), histone de­acetyl­ases (Richon, 2006[Richon, V. M. (2006). Br. J. Cancer, 95, S2-S6.]; Krennhrubec et al., 2007[Krennhrubec, K., Marshall, B. L., Hedglin, M., Verdin, E. & Ulrich, S. M. (2007). Bioorg. Med. Chem. Lett. 17, 2874-2878.]), or ureases (Xiao et al., 2013[Xiao, Z.-P., Peng, Z.-P., Dong, J.-J., Deng, R.-C., Wang, X.-D., Ouyang, H., Yang, P., He, J., Wang, W.-F., Zhu, M., Peng, X.-C., Peng, W.-X. & Zhu, H.-L. (2013). Eur. J. Med. Chem. 68, 212-221.]; Krajewska, 2009[Krajewska, B. (2009). J. Mol. Catal. B Enzym. 59, 9-21.]; Shi et al., 2016[Shi, W.-K., Deng, R.-C., Wang, P.-F., Yue, Q.-Q., Liu, Q., Ding, K.-L., Yang, M.-H., Zhang, H.-Y., Gong, S.-H., Deng, M., Liu, W.-R., Feng, Q.-J., Xiao, Z.-P. & Zhu, -L. (2016). Bioorg. Med. Chem. 24, 4519-4527.]). In our previous work, we have synthesized, characterized and investigated some physical-chemical properties of zinc(II) aromatic hydroxamates (Gonçalves et al., 2019[Gonçalves, B. L., Ramos, D. F., Halicki, P. C. B., da Silva, P. E. A. & Vicenti, J. R. M. (2019). Chemical Data Collections, 22, 100240-100248.]) and report here the crystal structure of [Zn(C7H5N2O4)2(C2H6OS)2] or [Zn(NBZH)2(DMSO)2].

A slightly distorted octa­hedral environment around the zinc(II) cation (site symmetry [\overline{1}]) is generated by symmetry operation 2 − x, −y, −z, leading to an all-trans configuration of the two ligands (Fig. 1[link]). In the mol­ecular structure, the O-bound DMSO mol­ecule has a distance of 2.3473 (12) Å for Zn1—O5, indicating an elongation along the axial position. The O,O′-chelating NBZH ligand shows shorter distances of 2.0029 (11) Å for Zn1—O1 and 2.0675 (11) Å for Zn1—O2 in the equatorial positions. The nitro group attached to the NBZH ligand is almost planar with the aromatic ring, displaying a dihedral angle of 3.2 (2)°.

In the crystal structure, discrete mol­ecular units of [Zn(NBZH)2(DMSO)2] (Fig. 2[link]) are packed along the [010] and [001] directions. The inter­molecular inter­actions collated in Table 1[link] are suggestive of two weak non-classical C—H⋯O hydrogen bonds involving di­methyl­sulfoxide mol­ecules. As shown in Fig. 3[link], the hydroxamate fragment plays a dominant role in the packing through an N—H⋯O5 hydrogen bond of medium strength along [100] (Table 1[link]). These structural features generate a three-dimensional supra­molecular network that was further investigated by Hirshfeld surface analysis (Fig. 4[link]), as determined with CrystalExplorer (Turner et al., 2017[Turner, M. J., McKinnon, J. J., Wolff, S. K., Grimwood, D. J., Spackman, P. R., Jayatilaka, D. & Spackman, M. A. (2017). CrystalExplorer17. University of Western Australia. https://hirshfeldsurface.net]). The results indicate a significant contribution by O⋯H contacts, corresponding to 43.1% of the two-dimensional fingerprint plots. H⋯H and C⋯H contacts are also observed, covering 30.1% and 11.6% of the isosurface, respectively, followed by C⋯C (2.9%), S⋯H (2.6%) and N⋯H (1%) inter­actions.

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.
