A novel topologically frustrated pentanuclear cluster helicate [{Cu II (μ‐L) 3 } 2 Cu II 3 (μ 3 ‐OH)] 3+ (L − =3,5‐bis(2‐pyridyl)pyrazolate) has been synthesized and characterized. This cluster has a helical arrangement of ligands around the central metal core. Dzyaloshinsky–Moriya interactions are essential components to observe a gradual magnetization and forbidden transitions of high‐field/multi‐frequency (HF/MF)‐ESR. The origin of the magnetic anisotropy of this compound is influenced by its helical spin structure, and consequently, the Cu 5 ‐cluster helicate introduces a unique magnetic anisotropy. This observation is a direct evidence of the topological part of the new spin phase in a magnetic system.
