Slow relaxation and magnetic coupling of magnetization in 3D CoII2-xZnIIx chain-based coordination frameworks with mixed double azide-tetrazolate bridges

Five 3D random bimetallic compounds based on azide-tetrazolate bridged Co2-xZnx chains are obtained. The CoII compound exhibits the coexistence of antiferromagnetic ordering and slow magnetic dynamics while bimetallic compounds depress the spin slow dynamics.171
