The 2:1 adduct of 8-hydroxyquinoline N-oxide and diaquabis(8-hydroxyquinoline N-oxide)dithiocyanatocobalt(II)

S.-G. Zhang, H.-Y. Xu and J.-M. Shi

Abstract: In the crystal structure of the title adduct, [Co(NCS)₂(C₉H₇NO₂)₂(H₂O)₂]·2C₉H₇NO₂, the uncoordinated 8-hydroxyquinoline molecules and complex molecules are connected by intermolecular O-HO and C-HS hydrogen bonds. In the complex molecule, the Co^II atom lies on a crystallographic inversion centre and has a slightly distorted octahedral coordination geometry. In addition, weak - stacking interactions between the uncoordinated and coordinated ring systems, with ring-centroid separations of 3.7554 (18) Å, consolidate the crystal structure.
