چکیده
In the crystal structure of the title complex, [Cd(NCS)(2)(C(7)H(5)ClN(4))(2)](n), the Cd(II) atom lies on a crystallographic inversion center and assumes a distorted octa-hedral geometry. The 2-chloro-6-(1H-1,2,4-triazol-1-yl)pyridine mol-ecule acts as a terminal ligand. The thio-cyanate ligands function as μ(1,3)-bridging units connecting adjacent Cd(II) atoms with a separation of 5.7525 (11) Å, forming a one-dimensional chain along the a axis.
