5-Nitro-1,10-phenanthroline Usage And Synthesis

Chemical Properties

Light yellow to yellow-brown crystalline powder

Purification Methods

Crystallise the phenanthroline from *benzene/pet ether, until anhydrous. It also crystallises from H2O with m 202o, and EtOAc with m 203o. Its pK2 5 varies from 3.20 to 2.69 with varying MeOH/H2O ratios from 0 to 0.95 moles/L, and from 3.20 to 1.95 in varying EtOH/H2O ratios from 0 to 0.94 moles/L [Ram et al. J Prakt Chem 319 719 1977]. It forms complexes with Cu2+, Zn2+, In2+, Fe2+ , Co2+, Ni2+ . [Beilstein 23 III/IV 1682, 23/8 V 425.]
