Diaquabis[2,5-bis(4-pyridyl)-1,3,4-thiadiazole]dithiocyanatocobalt(II) dihydrate

M. Du and X.-J. Zhao

Abstract: In the crystal structure of mononuclear [Co(SCN)₂(L)₂(H₂O)₂]·2H₂O [L is 2,5-bis(4-pyridyl)-1,3,4-thiadiazole, C₁₂H₈N₄S], the Co^II atom exists in an octahedral environment composed of two N atoms of the SCN^- groups and two aqua ligands, along with the two N atoms from two monodentate L ligands that are positioned trans to each other. Hydrogen-bonding interactions between the mononuclear units and uncoordinated water molecules result in a two-dimensional supramolecular network structure. The Co atom lies on a special position of $\overline 1$ site symmetry.
