Abstract

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