“…2a). The bond angle and the bond lengths around the central Co atoms comparable to the previous literature showed that the tetrahedron is slightly distorted similar to C 10 H 26 N 4 Co (SCN) 4 55 and [Ni(SCN) 4 ] 2(C 5 H 7 N 2 ) 56 (Table S1).…”

The cobalt (II) complexes have been synthesized from the reaction of the cationic entities (3,4-dimethylaniline (1) and histamine (2)) with metallic salt CoCl2⋅6H2O and thiocyanate ion (SCN−) as a ligand in H2O/ethanolic solution and processing by the evaporation crystal growth method at room temperature to get crystals. The synthesized complex has been fully characterized by single-crystal X-ray diffraction. UV–Visible, FTIR spectroscopy, TGA analysis, and DFT circulations were also performed. The crystal structural analysis reveals that the solid (1) {[Co(SCN)4] (C8H12N)3}·Cl crystallizes in the monoclinic system with the space group P21/n and the solid (2) {[Co(SCN)4](C5H11N3)2}·2Cl crystallizes in the monoclinic space group P21/m. Metal cations are joined into corrugated chains parallel to the b-axis direction in (1) and (2) by four thiocyanate anions. The crystal structures of (1) and (2) were calculated using XRPD data, indicating that they are closely connected to the DRX mono-crystal results. Different interactions pack the system into a ring formed by N–H⋯Cl and N–H⋯S hydrogen bonds. C–H⋯π and the π⋯π stacking of anilinuim ring for (1) and N–H⋯S intermolecular interactions for (1) and (2) increase the crystals' robustness. Hirshfeld surface analysis cum 2D fingerprint plots visualize the main intermolecular interactions with their contributions in the solid-state phase. The molecular geometries of both complexes obtained from the crystal structure were used for quantum chemical calculation. Here, frontier orbital analysis and electrostatic potential illustrate the chemical reactivities of metal–organic complexes. QTAIM and NCI analysis reveal the strength of interactions at the electronic level.

“…3 e1, 4e1, 5e1, and 6e1 show the convection that results from the stirring effect of the MF in blue regions. It was reported that [Ni(SCN) 4 ] 2- [ 23 ] and [Fe(SCN) 4 ] - [ 24 ] complex ions were formed by SCN − ions coordinating with Ni(Ⅱ) and Fe (Ⅲ) [ 25 ]. The concentration drops due to the creation of complex ions, and F L produces convection of the electrolyte containing complex ions in the blue regions.…”

“…According to Fig. 3, the central ion of all complexes is bonded with two N atoms from two 4-NH 2 py molecules and two anions as the ligands to form distorted tetrahedral geometry [8,[27][28][29]. While the bond length of Zn-N pyridine in all complexes has a similar bond length, the angle between N-Zn-N has different distortion depending on ligands [30] (Fig.…”

Three zinc(II) complexes containing 4-aminopyridine (4-NH2py) [Zn(4-NH2py)2(NCS)2] (1), [Zn(4-NH2py)2Cl2] (2), and [Zn(4-NH2py)2(NCS)Cl] (3) were synthesized and characterized by FTIR and single crystal X-ray diffraction. All complexes adopt a slightly distorted tetrahedral geometry with different crystal packing. Complex 1 crystallizes in the orthorhombic Pmmn space group, complex 2 in the monoclinic C2/c space group, and complex 3 in the orthorhombic Pbca space group. Non-covalent interactions such as NC-S···H, -Cl···H, and µ-µ stacking interaction between 4-NH2py and other ligands (NCS− and Cl−) are observed in the crystals packing. In vitro, antibacterial screening of all complexes was evaluated against two bacteria (Escherichia coli and Staphylococcus aureus). The results show that 1 has the highest antibacterial activity than 2 and 3. This difference is due to differences in the interactions elicited by the anion ligands.
