We report on a comprehensive characterization of the newly synthesized Cu²⁺-based molecular magnet Cu(pz)₂ (2-HOpy)₂ K, as revealed by μ⁺SR. In applied magnetic fields, our ¹H-NMR data reveal a strong increase of the magnetic anisotropy, manifested by a pronounced enhancement of the transition temperature to commensurate long-range order at T_N = 2.8 K and 7 T.
