Potential cytotoxic and amoebicide activity of first row transition metal compounds with 2,9-bis-(2',5'-diazahexanyl)-1,1-phenanthroline (L1).

A new synthetic pathway was reported to obtain N6 donor ligand 2,9-bis-(2',5'-diazahexanyl)-1,10-phenanthroline (L1) and its coordination compounds of essential divalent metal ions Mn, Fe, Co, Ni, Cu and Zn. Complete characterization of all compounds was done with the conventional techniques. Crystal structures of [NiL1](PF(6))(2) and [ZnL1](PF(6))(2)·H(2)O were also reported.
