Complexes of n-substituted phenothiazines with ni(ii): synthesis, characterisation and their biological studies

New series of Nickel(II) complexes were synthesized and formulated as [M L L1(CH3COO)(H2O)2], and [M L L1 (CH3COO)H2O] where L=N-substituted phenothiazines and L1=1,10-phenanthroline. The newly synthesized complexes have been characterized by elemental analysis, molar conductance, UV-Visible, IR, mass spectra and magnetic properties. The spectral studies have shown that the complexes are paramagnetic and tentative structure has been proposed for the prepared complexes. The complexes were screened for antibacterial, antifungal and antioxidant activities, some of the complexes exhibit good biological activity.
