Bimetallic MOFs (H₃O)_x[Cu(MF₆)(pyrazine)₂] (4-x)H₂O (M = V⁴⁺, x = 0; M = Ga³⁺, x = 1): co-existence of ordered and disordered quantum spins in the V⁴⁺ system

Abstract

The title compounds are bimetallic MOFs containing [Cu(pyz)₂]²⁺ square lattices linked by MF₆ ^n- octahedra. In each, only the Cu²⁺ spins exhibit long-range magnetic order below 3.5 K (M = V⁴⁺) and 2.6 K (M = Ga³⁺). The V⁴⁺ spins remain disordered down to 0.5 K.
