Abstract
The title compound, catena-poly[[[2-(2-pyridinyl)-4,4,5,5-tetramethylimidazolin-1-oxyl]thiocyanatonickel(II)]-μ-thiocyanato], [Ni(NCS)2(C12H16N3O)]n, was prepared from the imino nitroxide radical (IM2py), nickel(II) nitrate and potassium thiocyanate. The crystal structure consists of neutral chains of [Ni(IM2py)(SCN)] units linked by further thiocyanate as bridges. The Ni—NCS—Ni chains form a zigzag structure. Each NiII ion is located in a distorted square-pyramidal environment. The basal plane positions are occupied by two N atoms from the imino nitroxide radical and two thiocyanate N atoms, one from the terminal thiocyanate group and the other from the bridging thiocyanate group. The apical position is occupied by an S atom from the bridging thiocyanate group.
