| Abstract: | Mono-ligand complexes MnLX2 (L = pyridine, 4-pyrrolidinopyridine, X = Cl, Br, I, NCS) have been prepared. The pyridine complexes contain only bridging halide and pseudohalide groups, whereas the 4-py complexes contain both bridging and terminal bound anions. Ethanol is coordinated in Mn(EtOH)X2 (X=C1, Br) and Mn(EtOH)2X2 (X=I, NCS). Although the MnLX2 complexes have the same stoichiometry as the Mn(PR3)X2complexes none show any activity towaxds binding dioxygen either in the solid state or in solution. |
