title: Bis(2-hydroxy-N'-isopropylidenebenzo-hydrazidato-κN',O)bis-(pyridine-κN)cobalt(II).
abstract: In the title complex, [Co(C(10)H(11)N(2)O(2))(2)(C(5)H(5)N)(2)], the Co(II) atom lies on a centre of symmetry and adopts a distorted cis-CoO(2)N(4) octa-hedral geometry. The two acetone salicyloylhydrazone ligands are deprotonated and act as N,O-bidentate monoanionic ligands, forming the equatorial plane, while the axial positions are occupied by two N atoms of two pyridine mol-ecules. The complex presents O-H⋯N and C-H⋯N intra-molecular hydrogen bonds. Inter-molecular C-H⋯N and C-H⋯O inter-actions are also present in the crystal.
