Crystal structure of bis[4'-(1,4,7,10-tetraoxa-13-azacyclopentadecan-13-yl)-2,2':6',2″-terpyridine]-cobalt(III) tris(perchlorate) methanol monosolvate monohydrate

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.
