A new pyrazole ligand, N , N -bis(2(1',5,5'-trimethyl-1 H ,1' H -[3,3'-bipyrazol]-1-yl)ethyl)propan-1-amine (L) was synthesized and characterized by 1 H-NMR, 13 C-NMR, FT-IR and HRMS. The coordination ability of the ligand has been employed for the construction of a new family of coordination complexes, namely: [Cu 2 LCl 4 ] (1), [ML(CH 3 OH)(H 2 O)](ClO 4 ) 2 (M II = Ni (2), Co (3)) and [FeL(NCS) 2 ] (4). The series of complexes were characterized using single-crystal X-ray diffraction, HRMS, FT-IR and UV-visible spectroscopy. Moreover, the iron(ii) analogue was investigated by 57 Fe Mössbauer spectroscopy and SQUID magnetometry. Single-crystal X-ray structures of the prepared complexes are debated within the framework of the cooperative effect of the hydrogen bonding network and counter anions on the supramolecular formations observed. Furthermore, within the context of biological activity surveys, these compounds were reviewed against different types of bacteria to validate their efficiency, including both Gram-positive as well as Gram-negative bacteria. Enhanced behaviour towards Fusarium oxysporum f. sp. albedinis fungi, were detected for 1 and 4.
