Co2+, Ni2+, Cu2+, Zn2+, Cd2+ and Hg2+ Complexes of Butanedione Hydrazones: Spectroscopic, Thermal and Biological Studies

Othman A. Al-Fulaij, Ahmed E. El-Sayed & Ahmed A. El-Asmy · Chemical Science International Journal · 2016

Complexes of Co2+, Ni2+, Cu2+, Zn2+, Cd2+ and Hg2+ with malonyl- and succinoyl bis(2,3-butanedionehydrazone) [MBH, SBH] have been synthesized and characterized. Single crystal of SBH was found monoclinic with space group of P121/c14. The MBH complexes have the formulae: [Co(MBH)C...
