摘要：

Bis(pyridine-2,6-dimethanol-N,O,O')cobalt(II) disaccharinate dihydrate, [Co(C7H9NO2)(2)](C7H4NO3S)(2).2H(2)O, (I), and bis(pyridine-2,6-dimethanol-N,O,O')copper(II) disaccharinate dihydrate, [Cu(C7H9NO2)(2)](C7H4NO3S)(2).2H(2)O, (II), collectively [M(dmpy)(2)](sac)(2).2H(2)O (where M is Co-II or Cu-II, 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 pi-pi-stacking interactions.
