Metal-hydrazide of the ligand Bis[(Z)-N-(naphthalene-1-yl methylene) aceto hydrazide] that was abbreviated as NNMAH. It was synthesized and identified and was prepared by the reaction of Bis [(E)-N-(3-nitrobenzylidene) isonicotino hydrazide] and Mn(NO3)2 in hexane with Diethyl ether. Characterization of the ligand and its complex were made by microanalyses, FT-IR, 1HNMR and UV–Visible spectroscopies. The biological property such as antitumor of this complex was studied. This new complex showed excellent anti-tumor activity against two kind of cancer cells that are K562 (human chronic myeloid leukemia) cells and Jurkat (human T lymphocyte carcinoma) cells. https://biomedpharmajournal.org/vol5no1/preparation-characterization-and-anti-cancer-activity-of-a-new-bisz-n-naphthalene-1-yl-methylene-aceto-hydrazide-mnii-complex/ Manganese (II) Bis[(Z)-N-(naphthalene-1-yl methylene) aceto hydrazide] Praparation
