One-dimensional manganese(II) complex with only end-to-end azide ligands: Crystal structure and magnetic characterization

A novel one-dimensional azido-bridged manganese(II) complex of formula [Mn(L)2(N3)](ClO4) 1 has been synthesized and characterized crystallographically and magnetically, where L is the bidentate Schiff base obtained from the condensation of pyridine-2-carbaldehyde with 4-methoxyl aniline. Complex 1 is of one-dimensional chain structure with single end-to-end azido bridges. Magnetic analysis reveals that the weak antiferromagnetic interaction is mediated by the single end-to-end azido bridge with the exchange parameter J = −6.60 cm−1.
