Bis[1,3-bis(benzimidazol-2-yl)-2-oxapropane]cobalt(II) dipicrate acetonitrile trisolvate

In the title compound, [Co(C16H14N4O)2](C6H2N3O7)2·3CH3CN, the CoII ion is located on a crystallographic twofold rotation axis and is coordinated in a slightly distorted tetrahedral environment by four N atoms from the two bidentate N-heterocycles. The crystal structure is stabilized by intermolecular N—H⋯O and N—H⋯N hydrogen bonds. One of the acetonitrile solvent molecules also lies on a twofold rotation axis.
