Crystal structure and Hirshfeld surface analysis of the ortho-rhom-bic polymorph of a ZnII complex with 3,5-di-nitro-benzoic acid and ethyl-enedi-amine.

ABSTRACT: During systematic investigations of the biological action enhancement of well known compounds, a new metal complex, namely, bis-(3,5-di-nitro-benzoato)(ethane-1,2-di-amine)zinc(II), [Zn(C7H3N2O6)2(C2H8N2)], was synthesized and the structure of its ortho-rhom-bic form has determined. The synthesis and crystal structure of the monoclinic polymorph has previously been reported [Ibragimov et al. (2020 ?). Rep. Uzb. Acad. Sci. 1, 45-50]. The zinc ion has a distorted tetra--hedral environment formed by two monodentate 3,5-di-nitro-benzoato anions and chelating ethyl-enedi-amine mol-ecule. In the crystal, the complex mol-ecules are linked by N-H?O and C-H?O hydrogen bonds into a two-dimensional network parallel to the ac plane. The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H?O/O?H (43.4%) and O?C/C?O (17.7%) inter-actions.
