| Abstract: | Two end-on azido-bridged Co(III) complexes, Co3(L1)2(μ1,1-N3)4(N3)2(OH2)(OCH2CH3)]·0.5H2O (1) and Co2(L2)2(μ1,1-N3)2(N3)2] (2), where L1 and L2 are the deprotonated form of 5-methoxy-2-(2-morpholin-4-ylethylimino)methyl]phenol and 2-ethoxy-6-(2-isopropylaminoethylimino)methyl]phenol,
respectively, were prepared and structurally characterized by physicochemical and spectroscopic methods and single crystal
X-ray determination. Complex (1) is a trinuclear Co compound, while complex (2) is a centrosymmetric dinuclear Co compound.
In both complexes, the Co atoms are in octahedral coordination. The preliminary biological tests show that the complexes have
excellent antibacterial activity. |
