Preparation, crystal structures and properties of zinc complexes containing Bis(oxazoline) ligand

Abstract Three zinc complexes ([(DMOX)ZnX 2 ], X = Cl (1) , Br (2) or I (3) ), where DMOX is 4,5-dihydro-2-(4,5-dihydro-4,4-dimethyloxazol-2-yl)-4,4-dimethyloxazole), have been fully characterized by single crystal X-ray diffraction, UV–vis, NMR and IR spectroscopy. Moreover, all zinc complexes showed activities in catalyzing hydrolysis of 4-nitrophenyl acetate (4-NA). And active species have been determined by pH titrations of [(DMOX)ZnI 2 ] in catalyzing hydrolysis of 4-NA.
