Abstract	A cresolic oxygen bridging ligand, 2,6-bis{[(2-hydroxybenzyl)(2-hydroxyethyl)amino]methyl}-4-methylphenol (L), has been synthesized and characterized. The coordination of ZnII ions with L gives a novel tetranuclear complex, [ZnII4(L−3H)2](ClO4)2·3.5H2O (I), which crystallizes in a triclinic system with space group P, a = 12.261(5) A, b = 13.887(6) A, c = 20.738(8) A, α = 89.996(7)°, β = 88.163(7)° and γ = 85.016(7)°. The cationic core of I is formed by four ZnII cations bridged by two cresolic and four phenolic oxygen atoms from two ligands. All four ZnII centers are pentacoordinated and adopt a distorted square pyramid geometry. ESMS and 1H NMR data indicate that I is stable in solution, and the fluorescence measurement demonstrates that it has strong fluorescence at λex = 298 nm. The fluorescent complex can selectively sense the dihydrogen phosphate anion in methanol, and the binding phenomenon can be monitored via UV-vis absorption changes and fluorescence quenching effects. The potential binding mode of I with H2PO4− has been studied by ESMS and 1H NMR spectroscopy.
