Résumé en anglais

Two new dicyanamide bridged complexes [Mn(μ1,5-dca)2(salicyh)2]n (1) and {[Ni(μ1,5-dca)(TTA)](ClO4)}n (2) (dca = dicyanamide, ; salicyh = salicylic hydrazide; TTA = triethylenetetramine) have been synthesised and structurally characterised. Both the compounds 1 and 2 consist in 1-D coordination polymers. In 1 the manganese atoms are doubly bridged by μ1,5-dca ligands, whereas in 2 the nickel atoms are bridged by a single μ1,5-dca ligand. The magnetic measurements indicate that whereas intrachain interactions take place between the metal ions for compound 1 (J = −0.26 cm−1), no evidence for any exchange coupling is found for compound 2< Réduire
