Poly[(μ2-3,6-di-4-pyridyl-1,2,4,5-tetra­zine)(μ2-thio­cyanato)copper(I)]

The title compound, [Cu(NCS)(C(12)H(8)N(6))](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-tetra-zine ligands and by the N and S atoms from two thio-cyanate ligands in a distorted tetra-hedral environment. The Cu atom and the thio-cyanate ligand occupy a crystallographic mirror plane m, and a crystallographic inversion centre is in the middle of the tetra-zine 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-tetra-zine ligands that bridge the Cu(I) centers, generating a two-dimensional network. There are π-π stacking inter-actions between the pyridine and tetra-zine rings (perpendicular distances of 3.357 and 3.418 Å), with a centroid-centroid distance of 3.6785 (16) Å.
