Abstract: The title compound, [Cu(NCS)(C12H8N6)]n, is a self-assembled two-dimensional metal-organic network. The Cu atom is linked by two N atoms from two 3,6-di-4-pyridyl-1,2,4,5-tetrazine ligands and by the N and S atoms from two thiocyanate ligands in a distorted tetrahedral environment. The Cu atom and the thiocyanate ligand occupy a crystallographic mirror plane m, and a crystallographic inversion centre is in the middle of the tetrazine ring, generating the zigzag fashion of the two-dimensional network. The infinite -Cu-SCN-Cu-SCN- chain is due to translational symmetry along the a axis. These chains are further connected through the 3,6-di-4-pyridyl-1,2,4,5-tetrazine ligands that bridge the CuI centers, generating a two-dimensional network. There are - stacking interactions between the pyridine and tetrazine rings (perpendicular distances of 3.357 and 3.418 Å), with a centroid-centroid distance of 3.6785 (16) Å.
