Two coordination polymers [Mn(L)(μ1,1–N3)2]2n.[Mn(H2O)2(μ1,1–N3)2]n (1) and [Cd(HL)(μ1,1–N3)2]n (2) have been synthesized from pyridine-2-carbaldehyde semicarbazone (HL) and azide ligands, characterized by FT-IR, UV–vis spectroscopy and X-ray crystallography. Single crystal X-ray diffraction revealed that 1 is a coordination polymer consisting of two infinite 1-D chains, where Mn centers are connected via two double end-on (EO) azide bridges. 2 is a coordination polymer consisting of a 1-D infinite chain, where Cd centers are connected via two double EO azide bridges. The electrochemistry of HL, 1 and 2! was studied by cyclic voltammetry. Magnetic susceptibility measurements indicate bulk ferromagnetic coupling for 1 below 5K. Antimicrobial activities of both compounds 1 and 2 were investigated.
