N2 - Two complexes [PyH][Ni(Mnt)2] (I) and [QlH][Ni(Mnt) 2] (II) (Mnt2- = maleonitriledithiolate, [PyH] + = pyridinium, [QlH]+ = quinolinium) were synthesized and characterized by elemental analysis and IR spectra. ESR spectra of polycrystalline samples collected at room temperature are isotropic with g = 2.039 for I and anisotropic with gz = 1.997, gy ≈ gx = 2.102 (gav = 2.068) for II. The magnetic susceptibility data of I and II have been measured in the temperature range of 2-300 K. The results obtained suggest the antiferromagnetic coupling interactions between neighboring Ni3+ ions for I and ferromagnetic coupling interactions for II, respectively. Based on the crystal structure analysis of I, the magnetic properties of two complexes were discussed.
