one fragment with the set of phenolate- and methoxy-oxygens from the adjacent one. The magnetic properties of the three complexes have been investigated in the temperature range 1.9–300 K. Weak antiferromagnetic interactions between the MnIII and MIII ions across the cyanido bridge were found: JMnM = −5.6 (1), −0.63 (2) and −2.4 cm−1 (3) the Hamiltonian being defined as H = −JSMn·SM.
