The heteroscorpionate ligand 2,2‐bis(3,5‐dimethylpyrazol‐1‐yl)‐1,1‐diphenylethanol, C 24 H 26 N 4 O, features in the solid state an intramolecular O—H…N hydrogen bond. A heteroscorpionate tungsten complex, cis ‐[2,2‐bis(3,5‐dimethylpyrazolyl)‐1,1‐diphenylethanolato]chloridodioxidotungsten(VI) tetrahydrofuran monosolvate, [W(C 24 H 25 N 4 O)ClO 2 ]·C 4 H 8 O, was prepared by the simple mixing of solutions of the ligand and WOCl 4 in tetrahydrofuran. The tungsten complex was isolated after standing for several weeks. The complex exhibits a κ 3 N , N ′, O ‐coordination of the ligand. This simple synthetic procedure allows access to the cis isomer in high yield without additional purification steps. The Hirshfeld surface analysis shows a change of the intermolecular contacts due to the coordination of the WO 2 Cl unit with the ligand molecule.
