M. Mikuriya et al., Monodentate, didentate, and tridentate ligation of a Schiff-base ligand ina tetranuclear zinc(II) complex, B CHEM S J, 74(1), 2001, pp. 99-100
A tetranuclear zinc(II) complex with 2,6-bis(salicylideneaminomethyl)-4-met
hylphenol (H3L), [Zn-4(L)(2)(pz)(2)]. 2CH(3)CN (Hpz = pyrazole), was synthe
sized and characterized by H-1 NMR spectroscopy and a single-crystal X-ray
diffraction method. Each Schiff-base L3- acts as a monodentate, a didentate
, and a tridentate ligand for four zinc atoms to form a Z-shaped tetranucle
ar structure.
