Di - Chlorido-bis-[aqua-(2,2′-bipyridine-2 N,N′)chloridocobalt(II)]

Abstract

The title complex, [Co2Cl4 (C10H 8N2)2 (H2O)2], is composed of two CoII atoms, each hexa-coordinated by three Cl atoms, one 2,2′-bipyridine (bpy) ligand and one water mol-ecule in a distorted octa-hedral geometry. Neighboring CoII atoms are linked together by two Cl bridges, forming a dinuclear CoII complex with inversion symmetry. There are inter-molecular O - H⋯Cl hydrogen bonds and inter-molecular π-π stacking inter-actions between adjacent bpy ligands [centroid-centroid distance = 3.617 (2) Å] in the structure. © 2009 Zhu et al.
