The title complex was prepared by reaction of 1,3-bis(4-nitrophenyl)triazene with Cd(II) acetate in methanol/NaOH. Single crystals were obtained from pyridine and belong to the monoclinic space group C2/c with the lattice constants a = 20.086(1), b = 16.600(1), c = 11.250(1)Å, β = 102.122(1)°. The crystal structure consists of discrete mononuclear complexes of C₂ symmetry, in which the Cd(II) ions have a distorted octahedral coordination environment. Two deprotonated 1,3-bis(4-nitrophenyl)triazenide ions act as N11-η¹, N13-η¹ bidentate ligands. Two neutral pyridine molecules in the cis position complete the coordination sphere of the metal ion. The complexes are linked to chains via intermolecular non-classical C-H…O hydrogen bonds.
