Dinuclear Ni(II)Mn(II) and Cu(II)Mn(II) complexes of the general formula [MMn(Lm,n)](ClO4)2 ((Lm,n)2−= (L2,3)2−, (L2,4)2−(L3,3)2−; M = Ni, Cu) are obtained as solvates, using the dinucleating macrocycles (Lm,n)2− (derived from the [2:1:1] condensation of 2,6-diformyl-4-methylphenol, NH2(CH2)mNH2 (m = 2–3) and NH2(CH2)nNH2 (n = 2−4). [NiMn(L2,3)](ClO4)2·2DMF crystallizes in the orthorhombic space group Pbca.
[NiMn(L2,4)](ClO4)2·2DMF crystallizes in the monoclinic space group P21/n.
In both complexes the Ni(II) and Mn(II) ions are bridged by two endogenous phenolic oxygens of the macrocycle, with the Ni---Mn intermetallic separation of 3.145(2)Å for the former and 3.111(3)Å for the latter. In each complex the Ni(II) resides at the N202 site with the ethylene lateral chain and assumes a planar geometry. The Mn(II) at the N202 site with the trimethylene or tetramethylene lateral chain assumes a distorted six-coordinate geometry together with two DMF molecules. The M(II)Mn(II) (M = Ni, Cu) complexes are electrochemically converted to M(I)Mn(II) and M(II)Mn(III) complexes which are characterized by visible spectroscopy.
