The asymmetric unit of the binuclear title compound, [Cd(2)(NCS)(4)(C(24)H(20)N(6))(2)], contains one half-mol-ecule, consisting of one Cd(2+) cation, two half 1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene (L) ligands and two SCN(-) anions. The dimeric cyclic mol-ecule is completed by crystallographic inversion symmetry. The Cd(2+) cation is coordinated by two N atoms from two SCN(-) anions and four N atoms from two symmetry-related L ligands, exhibiting a distorted octrahedral coordination. A two-dimensional supra-molecular network stacked parallel to [210] is finally formed by linking these dimers through weak π-π stacking inter-actions between the pyridine rings and benzene rings of adjacent dimers, with a plane-to-plane distance of 3.36 (6) Å and a centroid-centroid distance of 3.67 (2) Å. One of the thio-cyanate S atoms is equally disordered over two positions.
