The synthesis of complexes of the type [Cu(pAb)
(4,7-phen)(HzO)]2(NO3)2 (6), [Cu(pAb)(5-NOzphen)(
H20)]z(NO3)2 (7) and [Cu(pAb)(4,7-dph)
(HzO)]2(NO3)2 (8) was carried out by adding a
MeOH solution of the proper phenantroline to
an aqueous solution of 4-aminobenzoic acid.
Then, an aqueous solution of Cu(NO3)2"3H20
was added. The respective molar ratio in the reaction
mixture was 1 : 1 : 1. Small crystals of the compounds
separated and were air dried.
