A novel ligand was prepared by the reaction of aqueous solution of carbohydrazide with aqueous solution of perchlorate. Its molecular structure was characterized by elemental analysis, infrared spectrum and DSC analysis. The molecular structure of [Mn (CHZ) 3] (Cl O4) 2 was determined by X-ray four-circle diffraction analysis. The crystal belongs to the monoclinic space group P2 1 / n with unit cell parameters of a = 1.097 (2) nm, b = 0.8593 (1) nm, c = 2.1142 (3) nm, b = 1 0 0 .86 °, V = 1 .842 6 (5) nm3, Z = 4. The results showed that the carbonyl hydrazide coordinated to the central manganese ion via its carbonyl oxygen atom and one terminal nitrogen atom to form a five-membered ring structure. There are three such five-membered ring structures in the molecule, which makes the complex stable and has Potential for use as an energetic material.
