Özet

Bis(pyridine-2,6-dimethanol-N, O, O ′)cobalt(II) disaccharinate dihydrate, [Co(C7H9NO2)2](C7H4NO3S)2·2H2O, (I), and bis(pyridine-2,6-dimethanol-N, O, O ′)copper(II) disaccharinate dihydrate, [Cu(C7H9NO2)2](C7H4NO3S)2·2H2O, (II), collectively [M(dmpy)2](sac)2·2H2O (where M is CoII or CuII, sac is the saccharinate anion and dmpy is pyridine-2,6-dimethanol), are isostructural. The [M(dmpy)2]2+ cations exhibit distorted octahedral geometry in which the two neutral dmpy species act as tripodal N, O, O ′-tridentate ligands. The crystal packing is determined by hydrogen bonding, as well as by weak pyridine-saccharinate π-π-stacking interactions.
