3D Co(ii) coordination polymer with ferrimagnetic-like layers based on azide and tetrazolate bridges showing slow magnetic dynamics.

A novel 3D Co(ii) coordination polymer, [Co6(4-ptz)6(N3)6]n (1) (4-ptz = 4-(pyridinyl)tetrazole), was synthesized by in situ hydrothermal reaction and characterized magnetically. Compound 1 consists of ferrimagnetic-like Co(ii) layers with the title heterobridges and exhibits the spin-glass slow dynamics. The study on spin-glass behavior in mixed azide and tetrazolate bridged compounds is the first example. [ABSTRACT FROM AUTHOR]
