title: The role of coordinated solvent on Co(ii) ions in tuning the single molecule magnet properties in a {CoDy} system.
abstract: Three defect-dicubane coordination clusters related to our previously reported butterfly compound, [Co2Dy2(L)4(NO3)2(THF)2]·4THF (1) and formulated as [Co2Dy2(L)4(NO3)2(MeOH)2]·2CH2Cl2(2), [Co2Dy2(L)4(NO3)2(DMF)2]·2C2H6CO (3) and [Zn2Dy2(L)4(NO3)2(MeOH)2]·2CH2Cl2(4) were synthesised and characterised. All show typical SMM behaviour which is steered through the nature of the solvent molecule coordinated to the central 3d ions. The ZnDy, (4) provides experimental proof of the suggestion that in such CoDy compounds two major relaxation pathways can be important in determining the overall magnetic behaviour of CoII-4f systems.
