Abstract
Metal chelate formation of 1-phenazinemethanol (PMO), which has an aliphatic hydroxyl group, with various metal ions was examined. Synthesis of metal chelate compounds of PMO with Cu2+, Zn2+, and Ni2+ was carried out by refluxing in ethanol solution and the complexes were identified by elementary and infrared spectral analyses. The chelate of PMO is considered to be not so stable as that of 1-phenazinol having a phenolic group and the interaction between PMO and metal ions (Co2+, Fe2+, Mn2+) in 99.5% ethanol was investigated by spectrophotometry. Binding ratio of the chelates was found to be 1 : 1 and their structures are discussed.
