AB  - Extended linear complexes of manganese(II) with a bis-chelating nitronyl 
      nitroxide ligand, 
      2-(2-imidazolato)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-3-oxide-1-oxy 
      (NITIm), have been prepared where metallic and organic spin carriers alternate. 
      Depending on the deprotonating agent, the solvent, and the counteranion, the 
      species [Mn(NITIm)(H(2)O)(2)]CH(3)COO, 1, [Mn(NITIm)(DMSO)(2)]BPh(4), 2, 
      [Mn(NITIm)(H(2)O)(ImH)]NO(3), 3, and [Mn(NITIm)(NITImH)]ClO(4), 4, have been 
      obtained, which differ by the additional ligands completing the metal 
      coordination sphere. Complexes 1-3 are cis isomers and 4 is found as the mer 
      modification; in all compounds, one observes a regular alternation of Lambda and 
      Delta metal environments. Their magnetic properties are similar, with 
      Mn(II)-nitroxide interactions J approximately -45 cm(-)(1) (H = 
      -2JS(i)().S(j)()), and they display weak ferromagnetic properties below 5 K. 
      Canting of the manganese ions is responsible for these properties. Relevant 
      crystallographic parameters are as follows: 1, space group Fdd2, a = 16.713(1), b 
      = 40.111(3), c = 9.735(1), Z = 16; 2, space group Pca2(1), a = 30.328(3), b = 
      13.422(1), c = 9.589(1), Z = 4; 3, space group P2(1)/c, a = 9.787(2), b = 
      22.973(5), c = 9.671(2), beta = 117.32(3) degrees, Z = 4; 4, space group P2(1)/c, 
      a = 9.761(2), b = 28.668(5), c = 9.941(2), beta = 96.07(3) degrees, Z = 4.
