Abstract	In the present PhD Thesis we describe the synthesis, structures and magnetic properties ofheterometallic 3d-4f and homometallic 4f complexes. The employment of suitable organicligands (H3L1, H2L2, H2L3, H2L4 and HL5) in NiII/4f, CoII/III/4f, CuII/4f and 4f chemistry led to the isolation and characterization of sixteen new 3d-4f and 4f families with general formulas:1. [NiII6LnIII3(OH)6(HL1)6(NO3)3](Ln= GdIII (1), DyIII (2), ErIII(3)),2. [CuII7LnIII2(L1)4(HL1)2(OAc)4](Ln= GdIII (4), TbIII (5), DyIII (6), YIII (7)),3. [CoIII4LnIII2(HL1)4(L1)2(MeO)2(NO3)2(MeOH)2](Ln= GdIII (8), DyIII (9)),4. [CoIII4CoII2CeIV(HL1)4(L1)4] (10),5. [LnIII7(OH)2(L2)9 (aib)] (Ln= DyIII (11), GdIII (12), TbIII (13), HoIII (14), ErIII (15),TmIII (16), YbIII (17), ΥΙΙΙ(18)),6. [CeIII8CeIV13O8(OH)24(NO3)12(L2)12] (19),7. [NiII6LnIII8(OH)10(L2)6(aib)4(naphth)4(NO3)4(MeO)2](Ln= DyIII (20), GdIII (21), HoIII (22)),8. [NiII7LnIII2(HL1)2(L1)4(aib)2(NO3)2](Ln= DyIII (23),Gd (24), Tb (25), Y (26)),9. [LnIII(L3)(MeO)(MeOH)0.5]n (Ln= GdIII (27), TbIII (28), DyIII (29)),10. [LnIII(L3)(N3)0.75(MeO)0.25(MeOH)]n (Ln= GdIII (30), TbIII (31), DyIII (32)),11. [LnIII2(L4)3(MeOH)] (Ln= DyIII (33), GdIII (34)),12. [CoII6LnIII2(L5)9(OH)4(aib)3] (Ln= GdIII (35), DyIII (36)),13. [CoΙΙ7LnΙΙΙ(L5)9(OH)3(aib)3](ClO4)(NO3) (Ln= GdIII (37), DyIII (38)),14. [NiΙΙ6LnΙΙΙ2(L5)9(OH)3(aib)3(ΜeO)](Ln= GdIII (39), DyIII (40)),15. [NiΙΙ7LnΙΙΙ(L5)9(OH)3(aib)3](Ln= GdIII (41), DyIII(42)),16. [NiII6LnIII(L5)4(Htea)4](Ln= DyIII(44), GdIII (45), YIII(46)).The magnetic characterization of all complexes gave us insight into slow relaxationphenomena, the ground and excited spin states and the magnetic exchange interactionspresent in the complexes, as well as the ground state magnetic anisotropy axes for the DyIIIcenters.
