摘要:
The crystal structures of the title complexes, namely trans-bis-(isoquinoline-3-carboxylato-kappa(2) N,O)bis(methanol-kappaO)cobalt(II), [Co(C10H6NO2)(2)(CH3OH)(2)], and the corresponding nickel( II) and copper(II) complexes, [Ni(C10H6NO2)(2)-(CH3OH)(2)] and [Cu(C10H6NO2)(2)(CH3OH)(2)], are isomorphous and contain metal ions at centres of inversion. The three compounds have the same distorted octahedral coordination geometry, and each metal ion is bonded by two quinoline N atoms, two carboxylate O atoms and two methanol O atoms. Two isoquinoline-3-carboxylate ligands lie in trans positions, forming the equatorial plane, and the two methanol ligands occupy the axial positions. The complex molecules are linked together by O-H...O hydrogen bonds between the methanol ligands and neighbouring carboxylate groups.
