Four monnuclear Co(Ⅱ) and Fe(Ⅱ) complexes([Co(L1)2] (ClO4)2. (CH3CN) (1 ),[Fe(L1),] (ClO4): (H2O) (2 ), [Co(L2) ] (ClO4)2(3 ), [Fe(L2) ] (ClO4)2. 2H2O (4)(L1 = 4'-Pheny]-2, 2,: 6', 2"-terpyridine and L2 = N，N，N -tris (2 - (2-pyridylmethylimino) ethyl ) amine )were synthesized. The structures of complexes 1 and 3 were determined. Crystals of the two complexes belong to monoclinic space group and their cell parameters are: 1 a = 1. 0855(4) nm ,b= 1. 6201 (5) nm, c = 2. 5236(5) nm, β= 92. 63(2)°, V= 4. 433(1) nm3; 3 a =2. 8351 (8)nm, b = 1. 0670(3) nm, c = 1- 9255(5) nm, β= 101. 03(4)°, V= 5. 717(2) nm3. The redox potentials of complexes 2 and 4 are E = 0. 78 V and 0. 63 V, respectively and the maximal of their d-d transition absorption bands are located at 565 and 521 nm, respectively.
