Abstract
Four pyridinecarboxamide iron dicyanide building blocks and one MnIII compound have been employed to assemble cyanidebridged heterometallic complexes resulting in a series of trinuclear cyanidebridged FeIII–MnII complexes MnDMF2 MeOH2FebpbCN22·2DMF 1 MnMeOH4FebpmbCN22·2MeOH·2H2O 2 MnMeOH4FebpdmbCN22·2MeOH·2H2O 3 and MnMeOH4FebpClbCN22·4MeOH 4 bpb2− = 12bispyridine2carboxamidobenzenate bpmb2− = 12bispyridine2carboxamido4methylbenzenate bpdmb2− = 12bispyridine2carboxamido45dimethylbenzenate bpClb2− = 12bispyridine2carboxamido4chlorobenzenate Singlecrystal Xray diffraction analysis shows their similar sandwichlike structures in which the two cyanidecontaining building blocks act as monodentate ligands through one of their two cyanide groups to coordinate the MnII center Investigation of the magnetic properties of these complexes reveals antiferromagnetic coupling between the neighboring FeIII and MnII centers through the bridging cyanide group A best fit to the magnetic susceptibilities of complexes 1 and 3 gave the magnetic coupling constants J = −1592 and −1324 cm−1 respectively
