Bis[1,3-bis-(benzimidazol-2-yl)-2-oxa-propane]cobalt(II) dipicrate acetonitrile tris-olvate.

In the title compound, [Co(C(16)H(14)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·3CH(3)CN, the Co(II) ion is located on a crystallographic twofold rotation axis and is coordinated in a slightly distorted tetra-hedral environment by four N atoms from the two bidentate N-heterocycles. The crystal structure is stabilized by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds. One of the acetonitrile solvent mol-ecules also lies on a twofold rotation axis.
