The&lt;br /&gt;complexes have been characterized by elemental analysis, molar conductance, magnetic&lt;br /&gt;susceptibility measurements and spectral (IR, electronic, EPR and mass) analyses. The IR&lt;br /&gt;spectra of complexes suggested that ligand is coordinated to the metal ion through imine&lt;br /&gt;nitrogen atoms. On the basis of spectral studies, an octahedral and tetragonal geometry has&lt;br /&gt;been assigned for Mn(II) and Cu(II) complexes, respectively. EPR spectra of polycrystalline&lt;br /&gt;Mn(II) complexes gave an isotropic signal with g value centered around free electron g&lt;br /&gt;value. EPR spectra of Mn(II) complexes in DMSO showed hyperfine splitting containing six&lt;br /&gt;lines, whereas EPR spectra of polycrystatalline Cu(II) complexes showed anisotropic&lt;br /&gt;signal. Conductivity measurements support the non electrolytic nature of the complexes.&lt;br /&gt;Magnetic moment data suggest that reported complexes are paramagnetic and of high spin&lt;br /&gt;type. All the examined complexes have also been tested in vitro against a number of&lt;br /&gt;pathogenic fungi. Results indicated that the complexes exhibited good antifungal activities.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Keywords:&lt;/strong&gt; Macrocyclic, octahedral, antifungal, tetragonal, anisotropic.&lt;/p&gt;&lt;p&gt;DOI:&amp;nbsp; 10.3126/jncs.v25i0.3284&lt;br /&gt;&lt;em&gt;&lt;br /&gt;Journal of Nepal Chemical Society&lt;/em&gt; Volume 25, 2010 pp 46-52&lt;/p&gt;}, journal={Journal of Nepal Chemical Society}, author={Kumar, U. and Chandra, S.}, year={2010}, month={Jun.}, pages={46–52} }
