title: Crystal structure of bis-[4'-(1,4,7,10-tetra-oxa-13- aza-cyclo-penta-decan-13-yl)-2,2':6',2''-terpyridine]-cobalt(III) tris-(perchlorate) methanol monosolvate monohydrate.
abstract: 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 octa-hedron. 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 intra-molecular C-H⋯π inter-action is observed between the two terpyridine ligands. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds, a π-π stacking inter-action [centroid-centroid distance = 3.923 (7) Å] and a C-H⋯π inter-action connect the complex cation, the perchlorate anions and the two types of solvent molecules, forming a three-dimensional network.
