title: Composition dependence of magnetic relaxation for CoNi chain-based compounds with mixed double azide-tetrazolate bridges.
abstract: Seven isomorphous 2D CoNi (0 ≤ x ≤ 1) compounds based on ferromagnetic chains with mixed double [(μ-EO-N3)(μ-N-N-tetrazolate)] (EO = end-on) were synthesized and then structurally and magnetically characterized. They are formulated as [CoNi(L)(N3)(H2O)]·H2O (), (x = 1 (), 0.86 (), 0.74 (), 0.39 (), 0.14 (), 0.10 (), 0 (); L = 3-(5-tetrazole)-N-oxide-pyridine). Magnetic studies revealed that the homo-metallic compounds ( and ) behave as metamagnets, while the hetero-metallic compounds () show interesting composition-dependent slow relaxation due to the synergy effect of Co(II) and Ni(II) ions.
