The syntheses, crystal structures and variable temperature (5-300 K) magnetic susceptibility measurements of two salen complexes of manganese(III) [where H2salen = N,N′-bis(salicylidene)-1,2-diaminoethane] having azido and dicyano argentate(I) as bridging ligands are reported. Both complexes belong to one-dimensional systems in which the azido functions as μ-(1,3) and Ag(CN)2- as ... NC- Ag-CN ... bridging ligands. The azido-bridged compound is antiferromagnetic with an intrachain interaction constant J = -4.52(4) cm-1 (Weng model) or J = 35.19(8) cm-1 (Fisher model), and it is a candidate to observe the Haldane gap in a S = 2 system. The silver cyanide bridged complex shows single ion behaviour of the Mn(III) ion, perhaps in combination with a very weak antiferromagnetic interaction.
