Manganese(II)-phenanthroline-azide compounds: Versatile Precursors as Ligands in Designing Heteropolymetallic Systems |
| |
| Abstract: | Two novel manganese(II) complexes, [Mn(phen)2N3·H2O]ClO4·H2O and Mn(phen)2(N3)2 have been synthesized by the reaction of Mn(ClO4)2·6H2O and Mn(CH3CO2)2·4H2O with NaN3 and phen in EtOH/H2O solution, respectively (where phen = 1,10-phenanthroline). Their crystal structures have been determined by X-ray diffraction. Both complex molecules have distorted octahedral geometry and two 1,10-phenanthroline molecules chelate to a Mn(II) atom with a cis-configuration. To [Mn(phen)2N3·H2O]ClO4·H2O, one nitrogen atom from an azide anion and one oxygen atom from a water molecule cis-coordinate to the Mn(II) atom while two nitrogen atoms occupy cis positions in Mn(phen)2(N3)2. These complexes are versatile precursors for the design of heteropolymetallic systems. |
