{Bis[4-(2-pyrid-yl)pyrimidin-2-yl] sulfide}dibromidocobalt(II).

ABSTRACT: The title compound, [CoBr(2)(C(18)H(12)N(6)S)], is a mononuclear complex in which a twofold rotation axis passes through the Co and S atoms. The Co(II) center is six-coordinated by four N atoms from one bis-[4-(2-pyrid-yl)pyrimidin-2-yl] sulfide (L) ligand and two bromide anions, forming an octa-hedral coordination geometry, where the four donor N atoms are located in the equatorial plane and the Br atoms occupy the axial positions. The sum of the bond angles around the Co atom in the equatorial plane is 360.5°, with the four N atoms and the central Co atom almost coplanar. In the crystal structure, the mononuclear units are linked by ?-? stacking inter-actions (the inter-planar distances are 3.469 and 3.533?Å, and the corresponding centroid-centroid distances are 3.791 and 3.896?Å) into a three-dimensional supra-molecular network.
