  Some complexes derived from zinc salicylate or 3,5-di-tert-butylsalicylate. The crystal structure of (2,2′-bipyridyl)(methanol)(O-salicylato)(O,O′-salicylato)zinc

  摘要：

  The aqua ligands of diaquabis(salicylato)zinc and diaquabis(3,5-di-tert-butylsalicylato)zinc are easily displaced generating related bis-pyridine and 2,2'-bipyridyl complexes. Attempts to recrystallise the tert-butylsalicylate from ethanol resulted in replacement of the aqua ligands by ethanol ligands. The attempted recrystallisation of (2,2'-bipyridyl)bis(salicylato)zinc from methanol led to the isolation of octahedral [Zn(O2CC6H4OH-2)(2)(bipy)(MeOH)] in which one salicylato ligand is coordinated in a monodentate fashion and the other in a bidentate chelating manner, both coordination modes involving carboxylate rather than hydroxyl oxygen coordination. The methanol is strongly bonded trans to a nitrogen, of the chelating 2,2'-bipyridyl and three further intramolecular six-membered hydrogen bonded rings are present, generated from interactions between the carboxyl and hydroxyl groups of the salicylate ligands and the hydroxyl group of the methanol ligand.

  The asymmetric unit of the title compound, [Zn(C7H5O3)(2)( C10H8N2)], contains one monomeric zinc complex. The Zn atom is coordinated to one 2,2'-bipyridyl ligand via both N atoms and to two salicylate anions (Hsal(-)) in a bidentate chelating manner involving carboxylate O-atom coordination. The complex exhibits a distorted octahedral geometry about the Zn-II atom, with the 'apical' positions occupied by one of the two N atoms of the bipyridyl ligand and an O atom from one Hsal(-) ligand; the Zn atom is 0.168 (1) Angstrom out of the 'basal' plane. Two intramolecular six-membered hydrogen-bonded rings are present, generated from interactions between the carboxyl and hydroxyl groups of the salicylate ligands. The crystal packing is governed by weak C - H...O and C - H...pi interactions.
