چکیده
The synthesis and characterization of mononuclear Co(II) complex based on 3,5-dimethyl-4-amino-1H-pyrazole are reported. IR UV/Vis spectroscopy the described. synthesis, results IR, NMR elemental analysis also X-ray [Co(C5H9N3)2Cl2] reveals that cobalt atom has a tetrahedral coordination environment formed by two nitrogen atoms belonging to ligands [Co1–N1 = 2.005(3) Co1–N5 2.006(3)Å] chlorine [Co1–Cl2 2.2400(11) Co1–Cl1 2.2863(12) Å]. In crystal structure molecules linked through intermolecular (N–H···N, N–H···Cl) intramolecular non-classical (С–H···Cl) hydrogen bonds. Hirshfeld surface contacts most important contributions for packing from H···H (47.1%) H···Cl/Cl···H (28.5%) contacts.
