A new (N 2 H 4 )WO 3 compound has been obtained by mixing WO 3 and aqueous hydrazine solution at room temperature for 24 h. The reaction is catalyzed by the presence of lithium. X‐ray, synchrotron and neutron diffraction techniques have shown that the material crystallizes in trigonal space group P 3 2 21 (No. 154). Chains of distorted WO 4 tetrahedra extend along the a axis of the unit cell, linked by a corner‐sharing oxygen atom: the N 2 H 4 are in the voids between them. The thermal characterization shows that this new compound is stable up to 220°C, greatly beyond the boiling point of N 2 H 4 (114°C); thus making it a promising candidate for catalysis or trapping applications.
