Abstract: Abstract: Based on the sugar-modified Schiff-base ligand derived from salicylaldehyde and benzyl 2-deoxy-2-amino-α-d-glucopyranoside (H2salagluc) the new mixed-ligand nickel(II) complex [Ni(Hsalagluc)(tptz)]ClO4 has been synthesized (tptz=2,4,6-tri-(2-pyridyl)-1,3,5-triazine). The X-ray crystal structure reveals a distorted octahedral geometry at the nickel(II) center with the rare 2,3-chelation of the trans-configured donor atoms of the carbohydrate backbone. Intermolecular hydrogen bonding leads to dimeric units of the complex cations. The supramolecular assembly of these units by π-stacking of the tptz coligands affords one-dimensional chains along the two fold screw axis. O–H⋯π(Ar) hydrogen bonding is observed for a methanol molecule of crystallization. Magnetic susceptibility measurements are consistent with a high-spin nickel(II) ion with a zero-field-splitting of D =−11.5cm−1 (g =2.311). [Copyright &y& Elsevier]
