Bis[tetrakis(pyridin-2-yl)methane-κ3N,N′,N′′]cobalt(II) tetrakis(thiocyanato-κN)cobaltate(II) methanol monosolvate

The title complex, [Co(C21H16N4)2][Co(NCS)4]·CH3OH, consists of one [Co{C(py)4}2]2+ complex cation [C(py)4 = tetrakis(pyridin-2-yl)methane], one [Co(NCS)4]2− complex anion and a methanol solvent molecule. In the cation, the CoII atom is coordinated by six N atoms of two C(py)4 ligands in a distorted octahedral geometry. In the anion, the CoII atom is coordinated by the N atoms of four NCS− ligands in a distorted tetrahedral geometry. The methanol molecule is disordered and was modelled over three orientations (occupancies 0.8:0.1:0.1). There are two weak hydrogen-bond-like interactions between the methanol solvent molecule and NCS− ligands of the anion [O...S = 3.283 (3) and 3.170 (2) Å]
