  In the title complex, [Co(NCS)2(C13H19N3O)(H2O)], the CoII
  ion is six-coordinated by the N,N0,N00-tridentate Schiff   base,
  the N atoms of two thiocyanate ligands and one water
  molecule in a distorted octahedral geometry. Intramolecular
  C—H N and C—H O hydrogen bonds occur. In the
  crystal, intermolecular O—H O, O—H S, C—H S and
  S S [3.5546 (18) A ° ] interactions result in an infinite   threedimensional

  The crystal structure of the title CoII complex is isostructural   with the previously reported NiII complex (Suleiman Gwaram
  et al., 2011). The Schiff base, prepared in situ, acts as an   N,N',N''-tridentate ligand towards the CoII ion to form two   fivemembered
  chelate rings with the metal atom. Two cis-located isothiocyanate   and one water molecule complete a distorted
  octahedral geometry around the Co(II) center. A similar   arrangement was observed in a related CoII complex (Sun et   al.,
  2007). The molecular structure contains intramolecular C—H···N   and C—H···O hydrogen bonds. In the crystal, the adjacent
  molecules are connected via O—H···O, O—H···S, C—H···S hydrogen   bonds into infinite layers parallel to the ac plane. The
  layers are further linked into a three-dimensional polymeric   structure through an S···S interaction [3.5546 (18) Å]   between
  S1 and S2 of the symmetry related molecule at –x+1, y - 1/2, -z +   3/2.
