@article{JKSA68044, author = {Putri Lestari and Nani Farida and I Wayan Dasna}, title = {Synthesis, Structure, Hirshfeld Surface Analysis, and Antibacterial Activity of [Ni(3-NH₂py)₄Cl₂] Complex (3-NH₂py = 3-aminopyridine)}, journal = {Jurnal Kimia Sains dan Aplikasi}, volume = {28}, number = {3}, year = {2025}, keywords = {Ni(II) complex; 3-aminopyridine; crystal structure; Hirschfeld surface; hydrothermal}, abstract = {Complex [Ni(3-NH 2 py) 4 Cl 2 ] was successfully synthesized through the reaction between NiCl 2 ·6H 2 O with 3-NH 2 py ligand with a mole ratio of 1:4 using the hydrothermal method at 120°C for 4 hours. The complex was characterized using the melting point test, electrical conductivity, FT-IR, and SC-XRD. The complex compound decomposed at 215°C. Typical absorption bands of 3-NH 2 py ligand appeared in the FT-IR spectrum of the complex at wave numbers 3375, 3323, 1585, and 1303 cm -1 , indicating the presence of -NH as , -NH s , C=N, and -C-NH 2 functional groups. The complex compound is an ionic compound that crystallizes in a distorted octahedral structure with a triclinic crystal system and space group P ī (a = 7.6428(8) Å, b = 8.5384(8) Å, c = 9.8610(13) Å and a = 73.920(4)°, b = 70.149(3)°, g = 71.036(2)°). The R-factor value is 4.48%, which shows the refinements are very close to the original structure. Based on the Hirshfeld surface analysis, the intermolecular interaction of N-H···Cl occurs between the H atom of the amine group and the ligand Cl in another molecule. Antibacterial activity tests against S. aureus and E. coli using chloramphenicol as a positive control. The results showed the inhibition zone diameters for both bacteria were 6.90 mm, higher than that of their free ligand.}, issn = {2597-9914}, pages = {106--114} doi = {10.14710/jksa.28.3.106-114}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/68044} }
