“…Moreover, the heterocyclic ligands with multiple donor atoms have been used widely in crystal engineering community because of the powerful chelating interaction to prepare complexes. [ 1,2 ] Over the years, their applications have received worldwide attention in outstanding optics materials, [ 3,4 ] molecular sensors [ 5 ] catalysis, [ 6,7 ] luminescent materials, [ 8 ] molecular magnetic materials, [ 9,10 ] and SOD‐like. [ 11,12 ] The lone pair of electrons effective on heterocyclic atoms can also be strongly involved in the formation of coordinated bond.…”

Two novel complexes [Zn(L)2·(NO3)2] (1) and [Ni(L)2·2H2O]·2CH3OH·(NO3)2 (2) (L = 2‐(2‐thiazolyl)‐4‐methyl‐1,2‐dihydroquinazoline‐N3‐oxide) were synthesized successfully and characterized by elemental analysis, as well as various spectroscopic techniques. Specifically, the photoluminescence behavior of complex 1 was explored in different solvents. The structural characterization of both complexes has been determined single‐crystal X‐ray diffraction. It revealed that the metals in 1 and 2 are chelated by two L ligands in centro‐symmetrically fashion and the complexes are counterbalanced by nitrate ions which act as coordinating species in 1, while two water molecules complete the Ni coordination sphere in 2. In the crystal structures, the adjacent molecules of complex 1 disclosed a ladder‐like 2‐D network and 3‐D supramolecular self‐assembly. Simultaneously, an infinite 1‐D chain, 2‐D layered skeleton, and even meter‐shaped 3‐D network of 2 was governed by molecular interactions (H–bonds, C–H⋯π). Most strikingly, the research of antibacterial activity proved that two complexes had good activity against two standard bacteria strains. To ascertain deeply the optimum geometric configurations and detect the frontier molecular orbital energy gaps, density functional theory (DFT) calculations were also investigated. Additionally, analyses of Hirshfeld surfaces (HS) and electrostatic potential (ESP) were also performed to quantify the presence of diverse noncovalent interactions.

The title compound, C17H25N3O3S2, hereafter 1, has been prepared and fully characterized by FTIR, 1H NMR and 13C NMR. Its crystal structure was determined by single‐crystal X‐ray diffraction. The crystal packing is stabilized by weak CH···O and CH···π interactions. The CLP‐Pixel method was used to quantify the energetically significant molecular dimers. The intermolecular contacts were identified and quantified using Hirshfeld surfaces (HS) and the corresponding fingerprint plots. The main contributions to the HS of 1 come from HH, OH/HO and CH/HC contacts, which cover about 93% of the total HS surface. The enrichment ratios showed that the favorable contacts accountable for the crystal packing are consistent with their contributions to the HS. Interaction region indicator (IRI) analysis was used to visualize the location and type of intermolecular contacts, allowing identify the CH···O contacts as van der Waals interactions. To visualize the 3D topology of interactions in the crystal structure, interaction energy values were used to construct energy framework diagrams, which showed that the dispersion energy dominates over other interaction energies, as expected for crystal packing governed by weak interactions. Finally, a combination of MEP surface, QTAIM and NCIplot analysis energetically confirmed the existence of CH···O and O···O dichalcogen interactions.
