ABSTRACT

The crystal structure of the title compound, [Co(NCS)2(C12H9NO)2(CH3OH)2], consists of cobalt(II) cations that are octa­hedrally coordinated by two N-terminal bonding thio­cyanato anions, two methanol mol­ecules and two 4-benzoyl­pyridine ligands into discrete complexes that are located on centres of inversion. These complexes are further linked by O—H⋯O hydrogen bonding between the hy­droxy H atom of the methanol ligand and the carbonyl O atom of the 4-benzoyl­pyridine ligand of a neighboring complex into layers parallel to (101). No pronounced inter­molecular inter­actions are observed between these layers.

Mentions: The asymmetric unit of the title compound, [Co(NCS)2(C12H9NO)2(CH3OH)2], consists of one cobalt(II) cation that is located on a center of inversion as well as of one thio­cyanate anion, one methanol mol­ecule and one neutral 4-benzoyl­pyridine ligand in general positions. The CoII cation is octa­hedrally coordinated by two terminal N-bonded anionic ligands, the O atoms of two methanol mol­ecules and the N atoms of two 4-benzoyl­pyridine ligands (Fig. 1 ▸). The Co—N bond lengths to the thio­cyanate anions are significantly shorter [2.062 (2) Å] than those to the pyridine N atom of the neutral 4-benzoyl­pyridine ligand [2.1875 (18) Å]. This is expected and in agreement with bond lengths reported in the closely related structure of [Co(NCS)2(C12H9NO)2(CH3CN)2] (Suckert et al., 2017 ▸) where methanol is replaced by aceto­nitrile, and also for related compounds reported in the literature (Soliman et al., 2014 ▸). The 4-benzoyl­pyridine ligand is not planar, with the phenyl rings inclined by 61.34 (9)°. This value is in agreement with those retrieved from literature which vary between 40.4 and 74.8° (Escuer et al., 2004 ▸).
