Structural evolution and zero-field SMM behaviour in ferromagnetically-coupled disk-type Co7 clusters bearing exclusively end-on azido bridges

Concise chemistry leads to a family of heptanuclear CoⅡ-clusters,[Co7(N3)12(CH3CN)12][Y2(NO3)4(piv)4]·2CH3CN(DC1)(pivH=pivalic acid),[Co7(N3)12(CH3CN)10(NO3)0.4(Cl)1.6]·4CH3CN(DC2)and[Co7(N3)12(CH3CN)10(NO3)2]·4CH3CN(DC3),in which the metal ions are exclusively bridged by end-on azido ligands to stabilize a beautiful disk-like topology.The resulting clusters exhibit interesting structural transformations and thermodynamically-distinct steady states verified by theoretical calcula-tions.Magnetic studies reveal the first observation of zero-field SMM behaviour in disk-like heptanuclear CoⅡ complexes.
