Abstract
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, N(CN) 2-; 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. © 2005 Elsevier B.V.
