Metal Acetate Hydrazines M CH3COO

Metal acetate hydrazines M(CH3COO)2(N2H4)2 (M = Mn, Co, Ni, Zn, and Cd) are synthesized by the reaction of freshly prepared metal acetate hydrates with excess hydrazine hydrate [11]. The reaction is instantaneous and yields hydrazine complexes as shown by (3.7)  

The products of the reaction are filtered, washed with alcohol first and then with diethyl ether, and dried over P2O5 in a vacuum desiccator. Table 3.7 lists infrared spectral data of these complexes. 

The metal ion in these complexes has been reported to possess an octahedral coordination and the acetate group is coordinated to the metal through an oxygen atom as a monodentate ligand. The large separation of 190 cm in the asymmetric and symmetric stretching frequencies of COO supports this argument.
