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?? inter-action is observed between the two terpyridine ligands. In the crystal, O-H?O and C-H?O hydrogen bonds, a ?-? stacking inter-action [centroid-centroid distance = 3.923?(7)?Å] and a C-H?? inter-action connect the complex cation, the perchlorate anions and the two types of solvent molecules, forming a three-dimensional network.
