Streszczenie

Two heterometallic polymers containing cations [Cu(en)2]2+ and either the [Mn(mal)2(H2O)2]2− (1) or [Mn2(succ)2Cl2]n2n (2) anions (mal = malonate and succ = succinate) were investigated by X-ray crystallography, high-field electron paramagnetic resonance (EPR) spectroscopy, and magnetic susceptibility measurements. Magnetic susceptibility and EPR spectra characteristic of antiferromagnetically coupled Mn2+−Mn2+ pairs were observed in 2, and the exchange integral J = 31 cm−1 (H = JS1S2) as well as the zero-field-splitting parameter D = −3.046 cm−1 in the triplet state of the dimanganese entity was determined.
