摘要

In the title compound, [Co(C25H30N4O4)2](ClO4)3·CH3OH·H2O, the metal atom is coordinated by two tridentate crown ether terpyridine ligands, forming a distorted CoN6 octa­hedron. The three pyridine rings in each crown–terpyridine ligand are approximately coplanar [maximum deviations = 0.088 (12) and 0.102 (15) Å] and the mean planes through the three pyridine rings are perpendicular to each other, making a dihedral angle of 89.95 (17)°. An intra­molecular C—H⋯π inter­action is observed between the two terpyridine ligands. In the crystal, O—H⋯O and C—H⋯O hydrogen bonds, a π–π stacking inter­action [centroid–centroid distance = 3.923 (7) Å] and a C—H⋯π inter­action connect the complex cation, the perchlorate anions and the two types of solvent molecules, forming a three-dimensional network.
