    Notes: Abstract A new monomeric manganese(II) nitrate complex with 2,2′-bipyridine (bpy), [Mn(bpy)2(NO3)(H2O)](NO3)·H2O, has been prepared and characterized by X-ray crystallography. The complex crystallizes in the triclinic space group $$P\bar 1$$ witha=9.721(3),b=14.691(5),c=8.578(3) Å, α=106.79(3), β=96.05(3), γ=82.55(3)°,V=1159.9 Å3 andZ=2. The structure comprises discrete cation [Mn(bpy)2(NO3)(H2O)]+ in which the metal atom is coordinated by a pair of bidentate bpy ligands [Mn−N=2.261(4)−2.299(4) Å], a unidentate nitrato [Mn−O=2.284(4) Å] and aqua [Mn−O=2.160(3) Å] ligands in a highly distorted octahedral arrangement.

    Notes: Abstract The square-planar complex [Cu(MIMH)(CH3CO2)](ClO4) (1) (MIMH = [(4-methylimidazol-5-yl)methylene]histamine) was prepared and structurally characterized. Complex 1 crystallizes in the monoclinic space group P21/n with a = 10.5331(10), b = 12.6177(10), c = 12.9773(10) Å, β = 107.710(10)°, V = 1643.0(2) Å3, and Z = 4. Single-crystal X-ray analysis reveals that the copper(II) atom in 1 has a distorted square-planar environment defined by three nitrogen atoms from the Schiff base ligand and one oxygen atom from the acetate group. The Cu—N bond lengths range from 1.950(3) to 2.015(3) Å and the Cu—O(1) bond length is 1.952(2) Å. The electronic spectra of 1 in aqueous solutions indicates that 1 forms adducts of square-pyramidal geometry with H2O. Cyclic voltammetry of 1 in DMF solution shows that there is some degradation of 1 upon reduction.
